Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706628, here are decompositions:

17 + 8706611 = 8706628
41 + 8706587 = 8706628
59 + 8706569 = 8706628
71 + 8706557 = 8706628
101 + 8706527 = 8706628
131 + 8706497 = 8706628
149 + 8706479 = 8706628
167 + 8706461 = 8706628

Showing the first eight; more decompositions exist.
