Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645584, here are decompositions:

5 + 8645579 = 8645584
41 + 8645543 = 8645584
107 + 8645477 = 8645584
257 + 8645327 = 8645584
317 + 8645267 = 8645584
347 + 8645237 = 8645584
443 + 8645141 = 8645584
461 + 8645123 = 8645584

Showing the first eight; more decompositions exist.
