This is the Goldbach Conjecture. The conjecture has been shown to hold up through 4 × 10^18, but has not yet been proven for all integers.
Anyway, just start listing them. A good place to start is near the midpoint of possibilities. Note that an odd number must be the sum of an even number and an odd number. The only even prime is 2.
80 = 39+41? no
80 = 37+43? yes
81 = 2 + 79
82 = 29+53
...
every number greater than 2 can be written as the sum of two prime numbers.
22=3+19 or 22=11+11
write the even number from 80 to 96 adbthe sum of two primes in atleast one way.
