Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646544, here are decompositions:

41 + 8646503 = 8646544
47 + 8646497 = 8646544
167 + 8646377 = 8646544
227 + 8646317 = 8646544
251 + 8646293 = 8646544
311 + 8646233 = 8646544
317 + 8646227 = 8646544
563 + 8645981 = 8646544

Showing the first eight; more decompositions exist.
