Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8610628, here are decompositions:

11 + 8610617 = 8610628
29 + 8610599 = 8610628
71 + 8610557 = 8610628
107 + 8610521 = 8610628
149 + 8610479 = 8610628
167 + 8610461 = 8610628
197 + 8610431 = 8610628
239 + 8610389 = 8610628

Showing the first eight; more decompositions exist.
