Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644494, here are decompositions:

17 + 8644477 = 8644494
37 + 8644457 = 8644494
41 + 8644453 = 8644494
43 + 8644451 = 8644494
97 + 8644397 = 8644494
163 + 8644331 = 8644494
167 + 8644327 = 8644494
193 + 8644301 = 8644494

Showing the first eight; more decompositions exist.
