Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8674428, here are decompositions:

19 + 8674409 = 8674428
29 + 8674399 = 8674428
31 + 8674397 = 8674428
67 + 8674361 = 8674428
79 + 8674349 = 8674428
89 + 8674339 = 8674428
97 + 8674331 = 8674428
107 + 8674321 = 8674428

Showing the first eight; more decompositions exist.
