Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541608, here are decompositions:
- 11 + 31541597 = 31541608
- 17 + 31541591 = 31541608
- 101 + 31541507 = 31541608
- 179 + 31541429 = 31541608
- 191 + 31541417 = 31541608
- 311 + 31541297 = 31541608
- 467 + 31541141 = 31541608
- 479 + 31541129 = 31541608
Showing the first eight; more decompositions exist.
