Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51186, here are decompositions:
- 17 + 51169 = 51186
- 29 + 51157 = 51186
- 53 + 51133 = 51186
- 127 + 51059 = 51186
- 139 + 51047 = 51186
- 193 + 50993 = 51186
- 197 + 50989 = 51186
- 229 + 50957 = 51186
Showing the first eight; more decompositions exist.
