Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535610, here are decompositions:
- 17 + 31535593 = 31535610
- 19 + 31535591 = 31535610
- 59 + 31535551 = 31535610
- 61 + 31535549 = 31535610
- 107 + 31535503 = 31535610
- 181 + 31535429 = 31535610
- 191 + 31535419 = 31535610
- 193 + 31535417 = 31535610
Showing the first eight; more decompositions exist.
