Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639002, here are decompositions:

3 + 8638999 = 8639002
5 + 8638997 = 8639002
11 + 8638991 = 8639002
149 + 8638853 = 8639002
269 + 8638733 = 8639002
311 + 8638691 = 8639002
419 + 8638583 = 8639002
521 + 8638481 = 8639002

Showing the first eight; more decompositions exist.
