Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545182, here are decompositions:
- 181 + 31545001 = 31545182
- 241 + 31544941 = 31545182
- 283 + 31544899 = 31545182
- 433 + 31544749 = 31545182
- 463 + 31544719 = 31545182
- 631 + 31544551 = 31545182
- 673 + 31544509 = 31545182
- 811 + 31544371 = 31545182
Showing the first eight; more decompositions exist.
