Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535622, here are decompositions:
- 29 + 31535593 = 31535622
- 31 + 31535591 = 31535622
- 71 + 31535551 = 31535622
- 73 + 31535549 = 31535622
- 193 + 31535429 = 31535622
- 199 + 31535423 = 31535622
- 211 + 31535411 = 31535622
- 241 + 31535381 = 31535622
Showing the first eight; more decompositions exist.
