Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545688, here are decompositions:
- 47 + 31545641 = 31545688
- 59 + 31545629 = 31545688
- 89 + 31545599 = 31545688
- 281 + 31545407 = 31545688
- 359 + 31545329 = 31545688
- 389 + 31545299 = 31545688
- 401 + 31545287 = 31545688
- 467 + 31545221 = 31545688
Showing the first eight; more decompositions exist.
