Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525712, here are decompositions:
- 13 + 31525699 = 31525712
- 61 + 31525651 = 31525712
- 103 + 31525609 = 31525712
- 109 + 31525603 = 31525712
- 223 + 31525489 = 31525712
- 433 + 31525279 = 31525712
- 499 + 31525213 = 31525712
- 919 + 31524793 = 31525712
Showing the first eight; more decompositions exist.
