Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57428, here are decompositions:

31 + 57397 = 57428
61 + 57367 = 57428
79 + 57349 = 57428
97 + 57331 = 57428
127 + 57301 = 57428
157 + 57271 = 57428
331 + 57097 = 57428
439 + 56989 = 57428

Showing the first eight; more decompositions exist.
