Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8674778, here are decompositions:

19 + 8674759 = 8674778
97 + 8674681 = 8674778
241 + 8674537 = 8674778
331 + 8674447 = 8674778
379 + 8674399 = 8674778
439 + 8674339 = 8674778
457 + 8674321 = 8674778
601 + 8674177 = 8674778

Showing the first eight; more decompositions exist.
