Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535694, here are decompositions:
- 13 + 31535681 = 31535694
- 23 + 31535671 = 31535694
- 37 + 31535657 = 31535694
- 61 + 31535633 = 31535694
- 101 + 31535593 = 31535694
- 103 + 31535591 = 31535694
- 191 + 31535503 = 31535694
- 227 + 31535467 = 31535694
Showing the first eight; more decompositions exist.
