Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627928, here are decompositions:

17 + 8627911 = 8627928
19 + 8627909 = 8627928
31 + 8627897 = 8627928
61 + 8627867 = 8627928
151 + 8627777 = 8627928
227 + 8627701 = 8627928
229 + 8627699 = 8627928
311 + 8627617 = 8627928

Showing the first eight; more decompositions exist.
