Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639674, here are decompositions:

11 + 8639663 = 8639674
83 + 8639591 = 8639674
107 + 8639567 = 8639674
167 + 8639507 = 8639674
233 + 8639441 = 8639674
293 + 8639381 = 8639674
311 + 8639363 = 8639674
383 + 8639291 = 8639674

Showing the first eight; more decompositions exist.
