Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525820, here are decompositions:
- 3 + 31525817 = 31525820
- 37 + 31525783 = 31525820
- 43 + 31525777 = 31525820
- 97 + 31525723 = 31525820
- 103 + 31525717 = 31525820
- 163 + 31525657 = 31525820
- 211 + 31525609 = 31525820
- 283 + 31525537 = 31525820
Showing the first eight; more decompositions exist.
