Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8713138, here are decompositions:

11 + 8713127 = 8713138
17 + 8713121 = 8713138
29 + 8713109 = 8713138
101 + 8713037 = 8713138
131 + 8713007 = 8713138
311 + 8712827 = 8713138
359 + 8712779 = 8713138
389 + 8712749 = 8713138

Showing the first eight; more decompositions exist.
