Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627784, here are decompositions:

7 + 8627777 = 8627784
43 + 8627741 = 8627784
71 + 8627713 = 8627784
83 + 8627701 = 8627784
103 + 8627681 = 8627784
157 + 8627627 = 8627784
167 + 8627617 = 8627784
173 + 8627611 = 8627784

Showing the first eight; more decompositions exist.
