Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645316, here are decompositions:

23 + 8645293 = 8645316
47 + 8645269 = 8645316
59 + 8645257 = 8645316
73 + 8645243 = 8645316
79 + 8645237 = 8645316
137 + 8645179 = 8645316
193 + 8645123 = 8645316
263 + 8645053 = 8645316

Showing the first eight; more decompositions exist.
