Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8674140, here are decompositions:

31 + 8674109 = 8674140
53 + 8674087 = 8674140
71 + 8674069 = 8674140
103 + 8674037 = 8674140
131 + 8674009 = 8674140
151 + 8673989 = 8674140
199 + 8673941 = 8674140
227 + 8673913 = 8674140

Showing the first eight; more decompositions exist.
