Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639088, here are decompositions:

37 + 8639051 = 8639088
61 + 8639027 = 8639088
89 + 8638999 = 8639088
97 + 8638991 = 8639088
137 + 8638951 = 8639088
151 + 8638937 = 8639088
179 + 8638909 = 8639088
197 + 8638891 = 8639088

Showing the first eight; more decompositions exist.
