Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525586, here are decompositions:
- 19 + 31525567 = 31525586
- 97 + 31525489 = 31525586
- 109 + 31525477 = 31525586
- 139 + 31525447 = 31525586
- 307 + 31525279 = 31525586
- 373 + 31525213 = 31525586
- 409 + 31525177 = 31525586
- 619 + 31524967 = 31525586
Showing the first eight; more decompositions exist.
