Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711642, here are decompositions:

73 + 8711569 = 8711642
109 + 8711533 = 8711642
151 + 8711491 = 8711642
241 + 8711401 = 8711642
283 + 8711359 = 8711642
463 + 8711179 = 8711642
571 + 8711071 = 8711642
631 + 8711011 = 8711642

Showing the first eight; more decompositions exist.
