Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57128, here are decompositions:

31 + 57097 = 57128
139 + 56989 = 57128
199 + 56929 = 57128
271 + 56857 = 57128
307 + 56821 = 57128
349 + 56779 = 57128
397 + 56731 = 57128
457 + 56671 = 57128

Showing the first eight; more decompositions exist.
