Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639046, here are decompositions:

19 + 8639027 = 8639046
47 + 8638999 = 8639046
79 + 8638967 = 8639046
109 + 8638937 = 8639046
113 + 8638933 = 8639046
137 + 8638909 = 8639046
179 + 8638867 = 8639046
193 + 8638853 = 8639046

Showing the first eight; more decompositions exist.
