Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51328, here are decompositions:

41 + 51287 = 51328
71 + 51257 = 51328
89 + 51239 = 51328
131 + 51197 = 51328
191 + 51137 = 51328
197 + 51131 = 51328
257 + 51071 = 51328
269 + 51059 = 51328

Showing the first eight; more decompositions exist.
