Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639170, here are decompositions:

17 + 8639153 = 8639170
47 + 8639123 = 8639170
107 + 8639063 = 8639170
173 + 8638997 = 8639170
179 + 8638991 = 8639170
233 + 8638937 = 8639170
317 + 8638853 = 8639170
443 + 8638727 = 8639170

Showing the first eight; more decompositions exist.
