Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8674138, here are decompositions:

29 + 8674109 = 8674138
47 + 8674091 = 8674138
89 + 8674049 = 8674138
101 + 8674037 = 8674138
149 + 8673989 = 8674138
197 + 8673941 = 8674138
227 + 8673911 = 8674138
461 + 8673677 = 8674138

Showing the first eight; more decompositions exist.
