Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542244, here are decompositions:
- 11 + 31542233 = 31542244
- 47 + 31542197 = 31542244
- 131 + 31542113 = 31542244
- 233 + 31542011 = 31542244
- 263 + 31541981 = 31542244
- 311 + 31541933 = 31542244
- 353 + 31541891 = 31542244
- 593 + 31541651 = 31542244
Showing the first eight; more decompositions exist.
