Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65040, here are decompositions:
- 7 + 65033 = 65040
- 11 + 65029 = 65040
- 13 + 65027 = 65040
- 29 + 65011 = 65040
- 37 + 65003 = 65040
- 43 + 64997 = 65040
- 71 + 64969 = 65040
- 89 + 64951 = 65040
Showing the first eight; more decompositions exist.
