Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621366, here are decompositions:

67 + 8621299 = 8621366
157 + 8621209 = 8621366
223 + 8621143 = 8621366
277 + 8621089 = 8621366
283 + 8621083 = 8621366
349 + 8621017 = 8621366
373 + 8620993 = 8621366
619 + 8620747 = 8621366

Showing the first eight; more decompositions exist.
