Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525656, here are decompositions:
- 5 + 31525651 = 31525656
- 7 + 31525649 = 31525656
- 47 + 31525609 = 31525656
- 53 + 31525603 = 31525656
- 67 + 31525589 = 31525656
- 89 + 31525567 = 31525656
- 103 + 31525553 = 31525656
- 157 + 31525499 = 31525656
Showing the first eight; more decompositions exist.
