Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638996, here are decompositions:

5 + 8638991 = 8638996
29 + 8638967 = 8638996
59 + 8638937 = 8638996
263 + 8638733 = 8638996
269 + 8638727 = 8638996
479 + 8638517 = 8638996
593 + 8638403 = 8638996
617 + 8638379 = 8638996

Showing the first eight; more decompositions exist.
