Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671942, here are decompositions:

5 + 8671937 = 8671942
23 + 8671919 = 8671942
131 + 8671811 = 8671942
173 + 8671769 = 8671942
233 + 8671709 = 8671942
311 + 8671631 = 8671942
353 + 8671589 = 8671942
359 + 8671583 = 8671942

Showing the first eight; more decompositions exist.
