Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645416, here are decompositions:

89 + 8645327 = 8645416
149 + 8645267 = 8645416
173 + 8645243 = 8645416
179 + 8645237 = 8645416
293 + 8645123 = 8645416
467 + 8644949 = 8645416
503 + 8644913 = 8645416
617 + 8644799 = 8645416

Showing the first eight; more decompositions exist.
