Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57312, here are decompositions:

11 + 57301 = 57312
29 + 57283 = 57312
41 + 57271 = 57312
43 + 57269 = 57312
53 + 57259 = 57312
61 + 57251 = 57312
71 + 57241 = 57312
89 + 57223 = 57312

Showing the first eight; more decompositions exist.
