Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645422, here are decompositions:

41 + 8645381 = 8645422
179 + 8645243 = 8645422
281 + 8645141 = 8645422
431 + 8644991 = 8645422
503 + 8644919 = 8645422
509 + 8644913 = 8645422
641 + 8644781 = 8645422
719 + 8644703 = 8645422

Showing the first eight; more decompositions exist.
