Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8713188, here are decompositions:

7 + 8713181 = 8713188
31 + 8713157 = 8713188
47 + 8713141 = 8713188
61 + 8713127 = 8713188
67 + 8713121 = 8713188
79 + 8713109 = 8713188
101 + 8713087 = 8713188
137 + 8713051 = 8713188

Showing the first eight; more decompositions exist.
