Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627678, here are decompositions:

61 + 8627617 = 8627678
67 + 8627611 = 8627678
97 + 8627581 = 8627678
109 + 8627569 = 8627678
151 + 8627527 = 8627678
181 + 8627497 = 8627678
211 + 8627467 = 8627678
307 + 8627371 = 8627678

Showing the first eight; more decompositions exist.
