Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539654, here are decompositions:
- 5 + 31539649 = 31539654
- 11 + 31539643 = 31539654
- 61 + 31539593 = 31539654
- 67 + 31539587 = 31539654
- 71 + 31539583 = 31539654
- 131 + 31539523 = 31539654
- 233 + 31539421 = 31539654
- 241 + 31539413 = 31539654
Showing the first eight; more decompositions exist.
