Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645064, here are decompositions:

11 + 8645053 = 8645064
17 + 8645047 = 8645064
41 + 8645023 = 8645064
53 + 8645011 = 8645064
73 + 8644991 = 8645064
101 + 8644963 = 8645064
107 + 8644957 = 8645064
137 + 8644927 = 8645064

Showing the first eight; more decompositions exist.
