Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534790, here are decompositions:
- 3 + 31534787 = 31534790
- 37 + 31534753 = 31534790
- 61 + 31534729 = 31534790
- 139 + 31534651 = 31534790
- 193 + 31534597 = 31534790
- 229 + 31534561 = 31534790
- 307 + 31534483 = 31534790
- 349 + 31534441 = 31534790
Showing the first eight; more decompositions exist.
