Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645022, here are decompositions:

11 + 8645011 = 8645022
13 + 8645009 = 8645022
31 + 8644991 = 8645022
59 + 8644963 = 8645022
73 + 8644949 = 8645022
103 + 8644919 = 8645022
109 + 8644913 = 8645022
149 + 8644873 = 8645022

Showing the first eight; more decompositions exist.
