Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639076, here are decompositions:

13 + 8639063 = 8639076
79 + 8638997 = 8639076
109 + 8638967 = 8639076
139 + 8638937 = 8639076
167 + 8638909 = 8639076
223 + 8638853 = 8639076
227 + 8638849 = 8639076
233 + 8638843 = 8639076

Showing the first eight; more decompositions exist.
