Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8686628, here are decompositions:

61 + 8686567 = 8686628
127 + 8686501 = 8686628
157 + 8686471 = 8686628
331 + 8686297 = 8686628
337 + 8686291 = 8686628
421 + 8686207 = 8686628
439 + 8686189 = 8686628
487 + 8686141 = 8686628

Showing the first eight; more decompositions exist.
