Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545838, here are decompositions:
- 89 + 31545749 = 31545838
- 101 + 31545737 = 31545838
- 197 + 31545641 = 31545838
- 227 + 31545611 = 31545838
- 239 + 31545599 = 31545838
- 431 + 31545407 = 31545838
- 509 + 31545329 = 31545838
- 521 + 31545317 = 31545838
Showing the first eight; more decompositions exist.
