Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639672, here are decompositions:

73 + 8639599 = 8639672
109 + 8639563 = 8639672
211 + 8639461 = 8639672
229 + 8639443 = 8639672
271 + 8639401 = 8639672
373 + 8639299 = 8639672
409 + 8639263 = 8639672
421 + 8639251 = 8639672

Showing the first eight; more decompositions exist.
