Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525752, here are decompositions:
- 29 + 31525723 = 31525752
- 53 + 31525699 = 31525752
- 101 + 31525651 = 31525752
- 103 + 31525649 = 31525752
- 149 + 31525603 = 31525752
- 151 + 31525601 = 31525752
- 163 + 31525589 = 31525752
- 199 + 31525553 = 31525752
Showing the first eight; more decompositions exist.
