Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51122, here are decompositions:
- 13 + 51109 = 51122
- 61 + 51061 = 51122
- 79 + 51043 = 51122
- 151 + 50971 = 51122
- 193 + 50929 = 51122
- 199 + 50923 = 51122
- 229 + 50893 = 51122
- 283 + 50839 = 51122
Showing the first eight; more decompositions exist.
