Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544944, here are decompositions:
- 3 + 31544941 = 31544944
- 173 + 31544771 = 31544944
- 227 + 31544717 = 31544944
- 383 + 31544561 = 31544944
- 401 + 31544543 = 31544944
- 647 + 31544297 = 31544944
- 773 + 31544171 = 31544944
- 887 + 31544057 = 31544944
Showing the first eight; more decompositions exist.
