Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51136, here are decompositions:

3 + 51133 = 51136
5 + 51131 = 51136
89 + 51047 = 51136
167 + 50969 = 51136
179 + 50957 = 51136
227 + 50909 = 51136
263 + 50873 = 51136
269 + 50867 = 51136

Showing the first eight; more decompositions exist.
