Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645450, here are decompositions:

7 + 8645443 = 8645450
19 + 8645431 = 8645450
43 + 8645407 = 8645450
97 + 8645353 = 8645450
109 + 8645341 = 8645450
157 + 8645293 = 8645450
181 + 8645269 = 8645450
193 + 8645257 = 8645450

Showing the first eight; more decompositions exist.
