Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645650, here are decompositions:

3 + 8645647 = 8645650
17 + 8645633 = 8645650
53 + 8645597 = 8645650
71 + 8645579 = 8645650
107 + 8645543 = 8645650
173 + 8645477 = 8645650
269 + 8645381 = 8645650
383 + 8645267 = 8645650

Showing the first eight; more decompositions exist.
