Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526386, here are decompositions:
- 113 + 31526273 = 31526386
- 173 + 31526213 = 31526386
- 179 + 31526207 = 31526386
- 197 + 31526189 = 31526386
- 317 + 31526069 = 31526386
- 467 + 31525919 = 31526386
- 569 + 31525817 = 31526386
- 587 + 31525799 = 31526386
Showing the first eight; more decompositions exist.
