Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627646, here are decompositions:

7 + 8627639 = 8627646
19 + 8627627 = 8627646
29 + 8627617 = 8627646
37 + 8627609 = 8627646
43 + 8627603 = 8627646
73 + 8627573 = 8627646
113 + 8627533 = 8627646
149 + 8627497 = 8627646

Showing the first eight; more decompositions exist.
