Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545790, here are decompositions:
- 41 + 31545749 = 31545790
- 47 + 31545743 = 31545790
- 53 + 31545737 = 31545790
- 149 + 31545641 = 31545790
- 167 + 31545623 = 31545790
- 179 + 31545611 = 31545790
- 191 + 31545599 = 31545790
- 383 + 31545407 = 31545790
Showing the first eight; more decompositions exist.
