Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535556, here are decompositions:
- 5 + 31535551 = 31535556
- 7 + 31535549 = 31535556
- 53 + 31535503 = 31535556
- 89 + 31535467 = 31535556
- 127 + 31535429 = 31535556
- 137 + 31535419 = 31535556
- 139 + 31535417 = 31535556
- 179 + 31535377 = 31535556
Showing the first eight; more decompositions exist.
