Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671984, here are decompositions:

3 + 8671981 = 8671984
5 + 8671979 = 8671984
17 + 8671967 = 8671984
47 + 8671937 = 8671984
173 + 8671811 = 8671984
263 + 8671721 = 8671984
353 + 8671631 = 8671984
401 + 8671583 = 8671984

Showing the first eight; more decompositions exist.
