Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525982, here are decompositions:
- 31 + 31525951 = 31525982
- 73 + 31525909 = 31525982
- 79 + 31525903 = 31525982
- 199 + 31525783 = 31525982
- 211 + 31525771 = 31525982
- 283 + 31525699 = 31525982
- 331 + 31525651 = 31525982
- 373 + 31525609 = 31525982
Showing the first eight; more decompositions exist.
