Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671918, here are decompositions:

11 + 8671907 = 8671918
107 + 8671811 = 8671918
149 + 8671769 = 8671918
179 + 8671739 = 8671918
197 + 8671721 = 8671918
401 + 8671517 = 8671918
419 + 8671499 = 8671918
449 + 8671469 = 8671918

Showing the first eight; more decompositions exist.
