Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57138, here are decompositions:

7 + 57131 = 57138
19 + 57119 = 57138
31 + 57107 = 57138
41 + 57097 = 57138
61 + 57077 = 57138
79 + 57059 = 57138
97 + 57041 = 57138
101 + 57037 = 57138

Showing the first eight; more decompositions exist.
