Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639684, here are decompositions:

37 + 8639647 = 8639684
223 + 8639461 = 8639684
241 + 8639443 = 8639684
271 + 8639413 = 8639684
283 + 8639401 = 8639684
337 + 8639347 = 8639684
421 + 8639263 = 8639684
433 + 8639251 = 8639684

Showing the first eight; more decompositions exist.
