Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668544, here are decompositions:

43 + 8668501 = 8668544
61 + 8668483 = 8668544
163 + 8668381 = 8668544
271 + 8668273 = 8668544
277 + 8668267 = 8668544
337 + 8668207 = 8668544
433 + 8668111 = 8668544
463 + 8668081 = 8668544

Showing the first eight; more decompositions exist.
