Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8674978, here are decompositions:

17 + 8674961 = 8674978
41 + 8674937 = 8674978
89 + 8674889 = 8674978
197 + 8674781 = 8674978
251 + 8674727 = 8674978
311 + 8674667 = 8674978
359 + 8674619 = 8674978
401 + 8674577 = 8674978

Showing the first eight; more decompositions exist.
