Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544818, here are decompositions:
- 47 + 31544771 = 31544818
- 59 + 31544759 = 31544818
- 101 + 31544717 = 31544818
- 257 + 31544561 = 31544818
- 401 + 31544417 = 31544818
- 521 + 31544297 = 31544818
- 647 + 31544171 = 31544818
- 719 + 31544099 = 31544818
Showing the first eight; more decompositions exist.
