Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545828, here are decompositions:
- 79 + 31545749 = 31545828
- 89 + 31545739 = 31545828
- 199 + 31545629 = 31545828
- 229 + 31545599 = 31545828
- 359 + 31545469 = 31545828
- 389 + 31545439 = 31545828
- 421 + 31545407 = 31545828
- 449 + 31545379 = 31545828
Showing the first eight; more decompositions exist.
