Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530728, here are decompositions:
- 67 + 31530661 = 31530728
- 79 + 31530649 = 31530728
- 139 + 31530589 = 31530728
- 157 + 31530571 = 31530728
- 241 + 31530487 = 31530728
- 277 + 31530451 = 31530728
- 337 + 31530391 = 31530728
- 379 + 31530349 = 31530728
Showing the first eight; more decompositions exist.
