Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539684, here are decompositions:
- 13 + 31539671 = 31539684
- 23 + 31539661 = 31539684
- 41 + 31539643 = 31539684
- 97 + 31539587 = 31539684
- 101 + 31539583 = 31539684
- 263 + 31539421 = 31539684
- 271 + 31539413 = 31539684
- 283 + 31539401 = 31539684
Showing the first eight; more decompositions exist.
