Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65128, here are decompositions:
- 5 + 65123 = 65128
- 17 + 65111 = 65128
- 29 + 65099 = 65128
- 101 + 65027 = 65128
- 131 + 64997 = 65128
- 191 + 64937 = 65128
- 227 + 64901 = 65128
- 251 + 64877 = 65128
Showing the first eight; more decompositions exist.
