Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535634, here are decompositions:
- 41 + 31535593 = 31535634
- 43 + 31535591 = 31535634
- 83 + 31535551 = 31535634
- 131 + 31535503 = 31535634
- 167 + 31535467 = 31535634
- 211 + 31535423 = 31535634
- 223 + 31535411 = 31535634
- 257 + 31535377 = 31535634
Showing the first eight; more decompositions exist.
