Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639236, here are decompositions:

17 + 8639219 = 8639236
29 + 8639207 = 8639236
59 + 8639177 = 8639236
83 + 8639153 = 8639236
113 + 8639123 = 8639236
173 + 8639063 = 8639236
239 + 8638997 = 8639236
269 + 8638967 = 8639236

Showing the first eight; more decompositions exist.
