Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8674220, here are decompositions:

7 + 8674213 = 8674220
43 + 8674177 = 8674220
151 + 8674069 = 8674220
211 + 8674009 = 8674220
223 + 8673997 = 8674220
307 + 8673913 = 8674220
439 + 8673781 = 8674220
619 + 8673601 = 8674220

Showing the first eight; more decompositions exist.
