Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711628, here are decompositions:

7 + 8711621 = 8711628
11 + 8711617 = 8711628
59 + 8711569 = 8711628
67 + 8711561 = 8711628
127 + 8711501 = 8711628
137 + 8711491 = 8711628
139 + 8711489 = 8711628
181 + 8711447 = 8711628

Showing the first eight; more decompositions exist.
