Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51228, here are decompositions:

11 + 51217 = 51228
29 + 51199 = 51228
31 + 51197 = 51228
59 + 51169 = 51228
71 + 51157 = 51228
97 + 51131 = 51228
157 + 51071 = 51228
167 + 51061 = 51228

Showing the first eight; more decompositions exist.
