Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535730, here are decompositions:
- 13 + 31535717 = 31535730
- 59 + 31535671 = 31535730
- 73 + 31535657 = 31535730
- 97 + 31535633 = 31535730
- 137 + 31535593 = 31535730
- 139 + 31535591 = 31535730
- 179 + 31535551 = 31535730
- 181 + 31535549 = 31535730
Showing the first eight; more decompositions exist.
