Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671894, here are decompositions:

83 + 8671811 = 8671894
173 + 8671721 = 8671894
197 + 8671697 = 8671894
263 + 8671631 = 8671894
311 + 8671583 = 8671894
383 + 8671511 = 8671894
431 + 8671463 = 8671894
467 + 8671427 = 8671894

Showing the first eight; more decompositions exist.
