Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645124, here are decompositions:

11 + 8645113 = 8645124
43 + 8645081 = 8645124
53 + 8645071 = 8645124
71 + 8645053 = 8645124
101 + 8645023 = 8645124
113 + 8645011 = 8645124
167 + 8644957 = 8645124
197 + 8644927 = 8645124

Showing the first eight; more decompositions exist.
