Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545040, here are decompositions:
- 17 + 31545023 = 31545040
- 71 + 31544969 = 31545040
- 257 + 31544783 = 31545040
- 269 + 31544771 = 31545040
- 281 + 31544759 = 31545040
- 383 + 31544657 = 31545040
- 467 + 31544573 = 31545040
- 479 + 31544561 = 31545040
Showing the first eight; more decompositions exist.
