Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645456, here are decompositions:

7 + 8645449 = 8645456
13 + 8645443 = 8645456
97 + 8645359 = 8645456
103 + 8645353 = 8645456
163 + 8645293 = 8645456
199 + 8645257 = 8645456
277 + 8645179 = 8645456
409 + 8645047 = 8645456

Showing the first eight; more decompositions exist.
