Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57126, here are decompositions:

7 + 57119 = 57126
19 + 57107 = 57126
29 + 57097 = 57126
37 + 57089 = 57126
53 + 57073 = 57126
67 + 57059 = 57126
79 + 57047 = 57126
89 + 57037 = 57126

Showing the first eight; more decompositions exist.
