Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639492, here are decompositions:

31 + 8639461 = 8639492
79 + 8639413 = 8639492
193 + 8639299 = 8639492
229 + 8639263 = 8639492
241 + 8639251 = 8639492
331 + 8639161 = 8639492
349 + 8639143 = 8639492
373 + 8639119 = 8639492

Showing the first eight; more decompositions exist.
