Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542004, here are decompositions:
- 3 + 31542001 = 31542004
- 23 + 31541981 = 31542004
- 71 + 31541933 = 31542004
- 101 + 31541903 = 31542004
- 113 + 31541891 = 31542004
- 311 + 31541693 = 31542004
- 353 + 31541651 = 31542004
- 521 + 31541483 = 31542004
Showing the first eight; more decompositions exist.
