Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638962, here are decompositions:

11 + 8638951 = 8638962
29 + 8638933 = 8638962
53 + 8638909 = 8638962
71 + 8638891 = 8638962
109 + 8638853 = 8638962
113 + 8638849 = 8638962
229 + 8638733 = 8638962
271 + 8638691 = 8638962

Showing the first eight; more decompositions exist.
