Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8674378, here are decompositions:

17 + 8674361 = 8674378
29 + 8674349 = 8674378
47 + 8674331 = 8674378
71 + 8674307 = 8674378
107 + 8674271 = 8674378
191 + 8674187 = 8674378
269 + 8674109 = 8674378
389 + 8673989 = 8674378

Showing the first eight; more decompositions exist.
