Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8713180, here are decompositions:

23 + 8713157 = 8713180
53 + 8713127 = 8713180
59 + 8713121 = 8713180
71 + 8713109 = 8713180
137 + 8713043 = 8713180
167 + 8713013 = 8713180
173 + 8713007 = 8713180
317 + 8712863 = 8713180

Showing the first eight; more decompositions exist.
