Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645180, here are decompositions:

67 + 8645113 = 8645180
109 + 8645071 = 8645180
127 + 8645053 = 8645180
151 + 8645029 = 8645180
157 + 8645023 = 8645180
223 + 8644957 = 8645180
277 + 8644903 = 8645180
307 + 8644873 = 8645180

Showing the first eight; more decompositions exist.
