Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536154, here are decompositions:
- 53 + 31536101 = 31536154
- 101 + 31536053 = 31536154
- 137 + 31536017 = 31536154
- 173 + 31535981 = 31536154
- 401 + 31535753 = 31536154
- 521 + 31535633 = 31536154
- 563 + 31535591 = 31536154
- 743 + 31535411 = 31536154
Showing the first eight; more decompositions exist.
