Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535814, here are decompositions:
- 5 + 31535809 = 31535814
- 17 + 31535797 = 31535814
- 61 + 31535753 = 31535814
- 67 + 31535747 = 31535814
- 73 + 31535741 = 31535814
- 97 + 31535717 = 31535814
- 157 + 31535657 = 31535814
- 181 + 31535633 = 31535814
Showing the first eight; more decompositions exist.
