Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639522, here are decompositions:

61 + 8639461 = 8639522
79 + 8639443 = 8639522
109 + 8639413 = 8639522
223 + 8639299 = 8639522
271 + 8639251 = 8639522
373 + 8639149 = 8639522
379 + 8639143 = 8639522
433 + 8639089 = 8639522

Showing the first eight; more decompositions exist.
