Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671378, here are decompositions:

11 + 8671367 = 8671378
17 + 8671361 = 8671378
47 + 8671331 = 8671378
71 + 8671307 = 8671378
227 + 8671151 = 8671378
251 + 8671127 = 8671378
281 + 8671097 = 8671378
311 + 8671067 = 8671378

Showing the first eight; more decompositions exist.
