Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545646, here are decompositions:
- 5 + 31545641 = 31545646
- 17 + 31545629 = 31545646
- 23 + 31545623 = 31545646
- 47 + 31545599 = 31545646
- 239 + 31545407 = 31545646
- 317 + 31545329 = 31545646
- 347 + 31545299 = 31545646
- 359 + 31545287 = 31545646
Showing the first eight; more decompositions exist.
