Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537022, here are decompositions:
- 19 + 31537003 = 31537022
- 31 + 31536991 = 31537022
- 79 + 31536943 = 31537022
- 151 + 31536871 = 31537022
- 193 + 31536829 = 31537022
- 199 + 31536823 = 31537022
- 229 + 31536793 = 31537022
- 409 + 31536613 = 31537022
Showing the first eight; more decompositions exist.
