Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645334, here are decompositions:

7 + 8645327 = 8645334
41 + 8645293 = 8645334
53 + 8645281 = 8645334
67 + 8645267 = 8645334
73 + 8645261 = 8645334
97 + 8645237 = 8645334
193 + 8645141 = 8645334
211 + 8645123 = 8645334

Showing the first eight; more decompositions exist.
