Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525756, here are decompositions:
- 107 + 31525649 = 31525756
- 149 + 31525607 = 31525756
- 167 + 31525589 = 31525756
- 257 + 31525499 = 31525756
- 359 + 31525397 = 31525756
- 389 + 31525367 = 31525756
- 467 + 31525289 = 31525756
- 593 + 31525163 = 31525756
Showing the first eight; more decompositions exist.
