Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677638, here are decompositions:

31 + 8677607 = 8677638
61 + 8677577 = 8677638
127 + 8677511 = 8677638
157 + 8677481 = 8677638
181 + 8677457 = 8677638
239 + 8677399 = 8677638
241 + 8677397 = 8677638
251 + 8677387 = 8677638

Showing the first eight; more decompositions exist.
