Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525686, here are decompositions:
- 29 + 31525657 = 31525686
- 37 + 31525649 = 31525686
- 79 + 31525607 = 31525686
- 83 + 31525603 = 31525686
- 97 + 31525589 = 31525686
- 149 + 31525537 = 31525686
- 197 + 31525489 = 31525686
- 239 + 31525447 = 31525686
Showing the first eight; more decompositions exist.
