Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639068, here are decompositions:

5 + 8639063 = 8639068
17 + 8639051 = 8639068
41 + 8639027 = 8639068
71 + 8638997 = 8639068
101 + 8638967 = 8639068
131 + 8638937 = 8639068
587 + 8638481 = 8639068
617 + 8638451 = 8639068

Showing the first eight; more decompositions exist.
