Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526686, here are decompositions:
- 17 + 31526669 = 31526686
- 53 + 31526633 = 31526686
- 83 + 31526603 = 31526686
- 197 + 31526489 = 31526686
- 263 + 31526423 = 31526686
- 479 + 31526207 = 31526686
- 599 + 31526087 = 31526686
- 617 + 31526069 = 31526686
Showing the first eight; more decompositions exist.
