Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525646, here are decompositions:
- 37 + 31525609 = 31525646
- 43 + 31525603 = 31525646
- 79 + 31525567 = 31525646
- 109 + 31525537 = 31525646
- 157 + 31525489 = 31525646
- 199 + 31525447 = 31525646
- 367 + 31525279 = 31525646
- 379 + 31525267 = 31525646
Showing the first eight; more decompositions exist.
