Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627684, here are decompositions:

3 + 8627681 = 8627684
67 + 8627617 = 8627684
73 + 8627611 = 8627684
103 + 8627581 = 8627684
151 + 8627533 = 8627684
157 + 8627527 = 8627684
181 + 8627503 = 8627684
211 + 8627473 = 8627684

Showing the first eight; more decompositions exist.
