Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57238, here are decompositions:

17 + 57221 = 57238
47 + 57191 = 57238
59 + 57179 = 57238
89 + 57149 = 57238
107 + 57131 = 57238
131 + 57107 = 57238
149 + 57089 = 57238
179 + 57059 = 57238

Showing the first eight; more decompositions exist.
