Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545610, here are decompositions:
- 3 + 31545607 = 31545610
- 11 + 31545599 = 31545610
- 281 + 31545329 = 31545610
- 293 + 31545317 = 31545610
- 311 + 31545299 = 31545610
- 389 + 31545221 = 31545610
- 419 + 31545191 = 31545610
- 491 + 31545119 = 31545610
Showing the first eight; more decompositions exist.
