Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8674440, here are decompositions:

31 + 8674409 = 8674440
41 + 8674399 = 8674440
43 + 8674397 = 8674440
79 + 8674361 = 8674440
97 + 8674343 = 8674440
101 + 8674339 = 8674440
109 + 8674331 = 8674440
191 + 8674249 = 8674440

Showing the first eight; more decompositions exist.
