Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671912, here are decompositions:

5 + 8671907 = 8671912
101 + 8671811 = 8671912
173 + 8671739 = 8671912
191 + 8671721 = 8671912
281 + 8671631 = 8671912
401 + 8671511 = 8671912
443 + 8671469 = 8671912
449 + 8671463 = 8671912

Showing the first eight; more decompositions exist.
