Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542014, here are decompositions:
- 3 + 31542011 = 31542014
- 13 + 31542001 = 31542014
- 37 + 31541977 = 31542014
- 43 + 31541971 = 31542014
- 157 + 31541857 = 31542014
- 277 + 31541737 = 31542014
- 307 + 31541707 = 31542014
- 337 + 31541677 = 31542014
Showing the first eight; more decompositions exist.
