Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646626, here are decompositions:

19 + 8646607 = 8646626
67 + 8646559 = 8646626
97 + 8646529 = 8646626
139 + 8646487 = 8646626
223 + 8646403 = 8646626
349 + 8646277 = 8646626
367 + 8646259 = 8646626
379 + 8646247 = 8646626

Showing the first eight; more decompositions exist.
