Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535672, here are decompositions:
- 79 + 31535593 = 31535672
- 331 + 31535341 = 31535672
- 409 + 31535263 = 31535672
- 439 + 31535233 = 31535672
- 499 + 31535173 = 31535672
- 541 + 31535131 = 31535672
- 613 + 31535059 = 31535672
- 661 + 31535011 = 31535672
Showing the first eight; more decompositions exist.
