Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545118, here are decompositions:
- 149 + 31544969 = 31545118
- 239 + 31544879 = 31545118
- 347 + 31544771 = 31545118
- 359 + 31544759 = 31545118
- 401 + 31544717 = 31545118
- 461 + 31544657 = 31545118
- 557 + 31544561 = 31545118
- 587 + 31544531 = 31545118
Showing the first eight; more decompositions exist.
