Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627688, here are decompositions:

7 + 8627681 = 8627688
61 + 8627627 = 8627688
71 + 8627617 = 8627688
79 + 8627609 = 8627688
107 + 8627581 = 8627688
127 + 8627561 = 8627688
191 + 8627497 = 8627688
241 + 8627447 = 8627688

Showing the first eight; more decompositions exist.
