Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542952, here are decompositions:
- 3 + 31542949 = 31542952
- 11 + 31542941 = 31542952
- 41 + 31542911 = 31542952
- 71 + 31542881 = 31542952
- 293 + 31542659 = 31542952
- 443 + 31542509 = 31542952
- 593 + 31542359 = 31542952
- 719 + 31542233 = 31542952
Showing the first eight; more decompositions exist.
