Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 49664, here are decompositions:
- 31 + 49633 = 49664
- 37 + 49627 = 49664
- 61 + 49603 = 49664
- 67 + 49597 = 49664
- 127 + 49537 = 49664
- 271 + 49393 = 49664
- 331 + 49333 = 49664
- 367 + 49297 = 49664
Showing the first eight; more decompositions exist.
