Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639004, here are decompositions:

5 + 8638999 = 8639004
7 + 8638997 = 8639004
13 + 8638991 = 8639004
37 + 8638967 = 8639004
53 + 8638951 = 8639004
67 + 8638937 = 8639004
71 + 8638933 = 8639004
113 + 8638891 = 8639004

Showing the first eight; more decompositions exist.
