Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537016, here are decompositions:
- 13 + 31537003 = 31537016
- 73 + 31536943 = 31537016
- 79 + 31536937 = 31537016
- 193 + 31536823 = 31537016
- 223 + 31536793 = 31537016
- 283 + 31536733 = 31537016
- 409 + 31536607 = 31537016
- 487 + 31536529 = 31537016
Showing the first eight; more decompositions exist.
