Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537108, here are decompositions:
- 11 + 31537097 = 31537108
- 59 + 31537049 = 31537108
- 107 + 31537001 = 31537108
- 149 + 31536959 = 31537108
- 191 + 31536917 = 31537108
- 389 + 31536719 = 31537108
- 401 + 31536707 = 31537108
- 479 + 31536629 = 31537108
Showing the first eight; more decompositions exist.
