Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65516, here are decompositions:
- 19 + 65497 = 65516
- 37 + 65479 = 65516
- 67 + 65449 = 65516
- 79 + 65437 = 65516
- 97 + 65419 = 65516
- 103 + 65413 = 65516
- 109 + 65407 = 65516
- 163 + 65353 = 65516
Showing the first eight; more decompositions exist.
