Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65020, here are decompositions:
- 17 + 65003 = 65020
- 23 + 64997 = 65020
- 83 + 64937 = 65020
- 101 + 64919 = 65020
- 149 + 64871 = 65020
- 167 + 64853 = 65020
- 227 + 64793 = 65020
- 239 + 64781 = 65020
Showing the first eight; more decompositions exist.
