Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646622, here are decompositions:

41 + 8646581 = 8646622
233 + 8646389 = 8646622
293 + 8646329 = 8646622
353 + 8646269 = 8646622
389 + 8646233 = 8646622
401 + 8646221 = 8646622
503 + 8646119 = 8646622
563 + 8646059 = 8646622

Showing the first eight; more decompositions exist.
