Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677644, here are decompositions:

37 + 8677607 = 8677644
67 + 8677577 = 8677644
163 + 8677481 = 8677644
167 + 8677477 = 8677644
191 + 8677453 = 8677644
251 + 8677393 = 8677644
257 + 8677387 = 8677644
277 + 8677367 = 8677644

Showing the first eight; more decompositions exist.
