Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536660, here are decompositions:
- 31 + 31536629 = 31536660
- 47 + 31536613 = 31536660
- 53 + 31536607 = 31536660
- 109 + 31536551 = 31536660
- 131 + 31536529 = 31536660
- 139 + 31536521 = 31536660
- 179 + 31536481 = 31536660
- 257 + 31536403 = 31536660
Showing the first eight; more decompositions exist.
