Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51126, here are decompositions:

17 + 51109 = 51126
67 + 51059 = 51126
79 + 51047 = 51126
83 + 51043 = 51126
137 + 50989 = 51126
157 + 50969 = 51126
197 + 50929 = 51126
233 + 50893 = 51126

Showing the first eight; more decompositions exist.
