Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645516, here are decompositions:

67 + 8645449 = 8645516
73 + 8645443 = 8645516
109 + 8645407 = 8645516
157 + 8645359 = 8645516
163 + 8645353 = 8645516
223 + 8645293 = 8645516
277 + 8645239 = 8645516
337 + 8645179 = 8645516

Showing the first eight; more decompositions exist.
