Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8713186, here are decompositions:

5 + 8713181 = 8713186
29 + 8713157 = 8713186
59 + 8713127 = 8713186
149 + 8713037 = 8713186
173 + 8713013 = 8713186
179 + 8713007 = 8713186
359 + 8712827 = 8713186
509 + 8712677 = 8713186

Showing the first eight; more decompositions exist.
