Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627636, here are decompositions:

19 + 8627617 = 8627636
67 + 8627569 = 8627636
103 + 8627533 = 8627636
109 + 8627527 = 8627636
139 + 8627497 = 8627636
163 + 8627473 = 8627636
307 + 8627329 = 8627636
337 + 8627299 = 8627636

Showing the first eight; more decompositions exist.
