Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641222, here are decompositions:

11 + 8641211 = 8641222
89 + 8641133 = 8641222
311 + 8640911 = 8641222
461 + 8640761 = 8641222
503 + 8640719 = 8641222
509 + 8640713 = 8641222
521 + 8640701 = 8641222
719 + 8640503 = 8641222

Showing the first eight; more decompositions exist.
