Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639206, here are decompositions:

29 + 8639177 = 8639206
53 + 8639153 = 8639206
83 + 8639123 = 8639206
179 + 8639027 = 8639206
239 + 8638967 = 8639206
269 + 8638937 = 8639206
353 + 8638853 = 8639206
479 + 8638727 = 8639206

Showing the first eight; more decompositions exist.
