Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545898, here are decompositions:
- 11 + 31545887 = 31545898
- 149 + 31545749 = 31545898
- 257 + 31545641 = 31545898
- 269 + 31545629 = 31545898
- 491 + 31545407 = 31545898
- 569 + 31545329 = 31545898
- 599 + 31545299 = 31545898
- 677 + 31545221 = 31545898
Showing the first eight; more decompositions exist.
