Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529720, here are decompositions:
- 3 + 31529717 = 31529720
- 43 + 31529677 = 31529720
- 97 + 31529623 = 31529720
- 127 + 31529593 = 31529720
- 163 + 31529557 = 31529720
- 181 + 31529539 = 31529720
- 199 + 31529521 = 31529720
- 241 + 31529479 = 31529720
Showing the first eight; more decompositions exist.
