Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645506, here are decompositions:

29 + 8645477 = 8645506
179 + 8645327 = 8645506
239 + 8645267 = 8645506
263 + 8645243 = 8645506
269 + 8645237 = 8645506
383 + 8645123 = 8645506
557 + 8644949 = 8645506
587 + 8644919 = 8645506

Showing the first eight; more decompositions exist.
