Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65512, here are decompositions:
- 89 + 65423 = 65512
- 131 + 65381 = 65512
- 383 + 65129 = 65512
- 389 + 65123 = 65512
- 401 + 65111 = 65512
- 449 + 65063 = 65512
- 479 + 65033 = 65512
- 509 + 65003 = 65512
Showing the first eight; more decompositions exist.
