Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544778, here are decompositions:
- 7 + 31544771 = 31544778
- 19 + 31544759 = 31544778
- 29 + 31544749 = 31544778
- 59 + 31544719 = 31544778
- 61 + 31544717 = 31544778
- 191 + 31544587 = 31544778
- 227 + 31544551 = 31544778
- 269 + 31544509 = 31544778
Showing the first eight; more decompositions exist.
