Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8674864, here are decompositions:

5 + 8674859 = 8674864
71 + 8674793 = 8674864
83 + 8674781 = 8674864
137 + 8674727 = 8674864
197 + 8674667 = 8674864
293 + 8674571 = 8674864
311 + 8674553 = 8674864
353 + 8674511 = 8674864

Showing the first eight; more decompositions exist.
