Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540710, here are decompositions:
- 11 + 31540699 = 31540710
- 17 + 31540693 = 31540710
- 31 + 31540679 = 31540710
- 41 + 31540669 = 31540710
- 53 + 31540657 = 31540710
- 59 + 31540651 = 31540710
- 67 + 31540643 = 31540710
- 73 + 31540637 = 31540710
Showing the first eight; more decompositions exist.
