Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542124, here are decompositions:
- 11 + 31542113 = 31542124
- 41 + 31542083 = 31542124
- 101 + 31542023 = 31542124
- 113 + 31542011 = 31542124
- 191 + 31541933 = 31542124
- 233 + 31541891 = 31542124
- 431 + 31541693 = 31542124
- 491 + 31541633 = 31542124
Showing the first eight; more decompositions exist.
