Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671828, here are decompositions:

17 + 8671811 = 8671828
59 + 8671769 = 8671828
89 + 8671739 = 8671828
107 + 8671721 = 8671828
131 + 8671697 = 8671828
197 + 8671631 = 8671828
239 + 8671589 = 8671828
311 + 8671517 = 8671828

Showing the first eight; more decompositions exist.
