Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627720, here are decompositions:

7 + 8627713 = 8627720
19 + 8627701 = 8627720
103 + 8627617 = 8627720
109 + 8627611 = 8627720
139 + 8627581 = 8627720
151 + 8627569 = 8627720
193 + 8627527 = 8627720
223 + 8627497 = 8627720

Showing the first eight; more decompositions exist.
