Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645066, here are decompositions:

13 + 8645053 = 8645066
19 + 8645047 = 8645066
37 + 8645029 = 8645066
43 + 8645023 = 8645066
103 + 8644963 = 8645066
109 + 8644957 = 8645066
139 + 8644927 = 8645066
163 + 8644903 = 8645066

Showing the first eight; more decompositions exist.
