Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533650, here are decompositions:
- 13 + 31533637 = 31533650
- 19 + 31533631 = 31533650
- 37 + 31533613 = 31533650
- 79 + 31533571 = 31533650
- 103 + 31533547 = 31533650
- 139 + 31533511 = 31533650
- 151 + 31533499 = 31533650
- 199 + 31533451 = 31533650
Showing the first eight; more decompositions exist.
