Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533590, here are decompositions:
- 3 + 31533587 = 31533590
- 19 + 31533571 = 31533590
- 43 + 31533547 = 31533590
- 73 + 31533517 = 31533590
- 79 + 31533511 = 31533590
- 139 + 31533451 = 31533590
- 181 + 31533409 = 31533590
- 211 + 31533379 = 31533590
Showing the first eight; more decompositions exist.
