Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711528, here are decompositions:

37 + 8711491 = 8711528
61 + 8711467 = 8711528
127 + 8711401 = 8711528
151 + 8711377 = 8711528
181 + 8711347 = 8711528
349 + 8711179 = 8711528
367 + 8711161 = 8711528
457 + 8711071 = 8711528

Showing the first eight; more decompositions exist.
