Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645276, here are decompositions:

7 + 8645269 = 8645276
19 + 8645257 = 8645276
37 + 8645239 = 8645276
97 + 8645179 = 8645276
163 + 8645113 = 8645276
223 + 8645053 = 8645276
229 + 8645047 = 8645276
313 + 8644963 = 8645276

Showing the first eight; more decompositions exist.
