Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627790, here are decompositions:

13 + 8627777 = 8627790
89 + 8627701 = 8627790
97 + 8627693 = 8627790
109 + 8627681 = 8627790
151 + 8627639 = 8627790
163 + 8627627 = 8627790
173 + 8627617 = 8627790
179 + 8627611 = 8627790

Showing the first eight; more decompositions exist.
