Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541896, here are decompositions:
- 3 + 31541893 = 31541896
- 5 + 31541891 = 31541896
- 263 + 31541633 = 31541896
- 389 + 31541507 = 31541896
- 467 + 31541429 = 31541896
- 479 + 31541417 = 31541896
- 599 + 31541297 = 31541896
- 653 + 31541243 = 31541896
Showing the first eight; more decompositions exist.
