Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639032, here are decompositions:

5 + 8639027 = 8639032
41 + 8638991 = 8639032
179 + 8638853 = 8639032
449 + 8638583 = 8639032
569 + 8638463 = 8639032
653 + 8638379 = 8639032
659 + 8638373 = 8639032
683 + 8638349 = 8639032

Showing the first eight; more decompositions exist.
