Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645252, here are decompositions:

13 + 8645239 = 8645252
73 + 8645179 = 8645252
139 + 8645113 = 8645252
181 + 8645071 = 8645252
199 + 8645053 = 8645252
223 + 8645029 = 8645252
229 + 8645023 = 8645252
241 + 8645011 = 8645252

Showing the first eight; more decompositions exist.
