Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57728, here are decompositions:

19 + 57709 = 57728
31 + 57697 = 57728
61 + 57667 = 57728
79 + 57649 = 57728
127 + 57601 = 57728
157 + 57571 = 57728
199 + 57529 = 57728
241 + 57487 = 57728

Showing the first eight; more decompositions exist.
