Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541950, here are decompositions:
- 17 + 31541933 = 31541950
- 47 + 31541903 = 31541950
- 59 + 31541891 = 31541950
- 257 + 31541693 = 31541950
- 317 + 31541633 = 31541950
- 353 + 31541597 = 31541950
- 359 + 31541591 = 31541950
- 443 + 31541507 = 31541950
Showing the first eight; more decompositions exist.
