Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544790, here are decompositions:
- 7 + 31544783 = 31544790
- 19 + 31544771 = 31544790
- 31 + 31544759 = 31544790
- 41 + 31544749 = 31544790
- 71 + 31544719 = 31544790
- 73 + 31544717 = 31544790
- 229 + 31544561 = 31544790
- 239 + 31544551 = 31544790
Showing the first eight; more decompositions exist.
