Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645518, here are decompositions:

41 + 8645477 = 8645518
137 + 8645381 = 8645518
191 + 8645327 = 8645518
251 + 8645267 = 8645518
257 + 8645261 = 8645518
281 + 8645237 = 8645518
509 + 8645009 = 8645518
569 + 8644949 = 8645518

Showing the first eight; more decompositions exist.
