Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644554, here are decompositions:

43 + 8644511 = 8644554
47 + 8644507 = 8644554
53 + 8644501 = 8644554
97 + 8644457 = 8644554
101 + 8644453 = 8644554
103 + 8644451 = 8644554
157 + 8644397 = 8644554
223 + 8644331 = 8644554

Showing the first eight; more decompositions exist.
