Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525590, here are decompositions:
- 23 + 31525567 = 31525590
- 37 + 31525553 = 31525590
- 53 + 31525537 = 31525590
- 101 + 31525489 = 31525590
- 113 + 31525477 = 31525590
- 193 + 31525397 = 31525590
- 211 + 31525379 = 31525590
- 223 + 31525367 = 31525590
Showing the first eight; more decompositions exist.
