Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525856, here are decompositions:
- 7 + 31525849 = 31525856
- 73 + 31525783 = 31525856
- 79 + 31525777 = 31525856
- 139 + 31525717 = 31525856
- 157 + 31525699 = 31525856
- 199 + 31525657 = 31525856
- 367 + 31525489 = 31525856
- 379 + 31525477 = 31525856
Showing the first eight; more decompositions exist.
