Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627628, here are decompositions:

11 + 8627617 = 8627628
17 + 8627611 = 8627628
19 + 8627609 = 8627628
47 + 8627581 = 8627628
59 + 8627569 = 8627628
67 + 8627561 = 8627628
101 + 8627527 = 8627628
131 + 8627497 = 8627628

Showing the first eight; more decompositions exist.
