Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645446, here are decompositions:

3 + 8645443 = 8645446
179 + 8645267 = 8645446
647 + 8644799 = 8645446
743 + 8644703 = 8645446
839 + 8644607 = 8645446
947 + 8644499 = 8645446
1049 + 8644397 = 8645446
1193 + 8644253 = 8645446

Showing the first eight; more decompositions exist.
