Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639044, here are decompositions:

17 + 8639027 = 8639044
47 + 8638997 = 8639044
53 + 8638991 = 8639044
107 + 8638937 = 8639044
191 + 8638853 = 8639044
311 + 8638733 = 8639044
317 + 8638727 = 8639044
347 + 8638697 = 8639044

Showing the first eight; more decompositions exist.
