Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671960, here are decompositions:

23 + 8671937 = 8671960
41 + 8671919 = 8671960
53 + 8671907 = 8671960
149 + 8671811 = 8671960
191 + 8671769 = 8671960
239 + 8671721 = 8671960
251 + 8671709 = 8671960
263 + 8671697 = 8671960

Showing the first eight; more decompositions exist.
