Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639176, here are decompositions:

5 + 8639171 = 8639176
23 + 8639153 = 8639176
53 + 8639123 = 8639176
113 + 8639063 = 8639176
149 + 8639027 = 8639176
179 + 8638997 = 8639176
239 + 8638937 = 8639176
443 + 8638733 = 8639176

Showing the first eight; more decompositions exist.
