Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535854, here are decompositions:
- 23 + 31535831 = 31535854
- 101 + 31535753 = 31535854
- 107 + 31535747 = 31535854
- 113 + 31535741 = 31535854
- 137 + 31535717 = 31535854
- 173 + 31535681 = 31535854
- 197 + 31535657 = 31535854
- 263 + 31535591 = 31535854
Showing the first eight; more decompositions exist.
