Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645940, here are decompositions:

13 + 8645927 = 8645940
41 + 8645899 = 8645940
53 + 8645887 = 8645940
137 + 8645803 = 8645940
151 + 8645789 = 8645940
167 + 8645773 = 8645940
179 + 8645761 = 8645940
181 + 8645759 = 8645940

Showing the first eight; more decompositions exist.
