Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544728, here are decompositions:
- 11 + 31544717 = 31544728
- 71 + 31544657 = 31544728
- 167 + 31544561 = 31544728
- 197 + 31544531 = 31544728
- 311 + 31544417 = 31544728
- 431 + 31544297 = 31544728
- 521 + 31544207 = 31544728
- 557 + 31544171 = 31544728
Showing the first eight; more decompositions exist.
