Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645300, here are decompositions:

7 + 8645293 = 8645300
19 + 8645281 = 8645300
31 + 8645269 = 8645300
43 + 8645257 = 8645300
61 + 8645239 = 8645300
229 + 8645071 = 8645300
271 + 8645029 = 8645300
277 + 8645023 = 8645300

Showing the first eight; more decompositions exist.
