Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532664, here are decompositions:
- 5 + 31532659 = 31532664
- 11 + 31532653 = 31532664
- 67 + 31532597 = 31532664
- 71 + 31532593 = 31532664
- 83 + 31532581 = 31532664
- 113 + 31532551 = 31532664
- 157 + 31532507 = 31532664
- 167 + 31532497 = 31532664
Showing the first eight; more decompositions exist.
