Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525612, here are decompositions:
- 3 + 31525609 = 31525612
- 5 + 31525607 = 31525612
- 11 + 31525601 = 31525612
- 23 + 31525589 = 31525612
- 59 + 31525553 = 31525612
- 113 + 31525499 = 31525612
- 191 + 31525421 = 31525612
- 233 + 31525379 = 31525612
Showing the first eight; more decompositions exist.
