Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639694, here are decompositions:

31 + 8639663 = 8639694
47 + 8639647 = 8639694
97 + 8639597 = 8639694
103 + 8639591 = 8639694
127 + 8639567 = 8639694
131 + 8639563 = 8639694
163 + 8639531 = 8639694
233 + 8639461 = 8639694

Showing the first eight; more decompositions exist.
