Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627668, here are decompositions:

29 + 8627639 = 8627668
41 + 8627627 = 8627668
59 + 8627609 = 8627668
107 + 8627561 = 8627668
227 + 8627441 = 8627668
239 + 8627429 = 8627668
251 + 8627417 = 8627668
311 + 8627357 = 8627668

Showing the first eight; more decompositions exist.
