Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671906, here are decompositions:

137 + 8671769 = 8671906
167 + 8671739 = 8671906
197 + 8671709 = 8671906
317 + 8671589 = 8671906
389 + 8671517 = 8671906
443 + 8671463 = 8671906
449 + 8671457 = 8671906
479 + 8671427 = 8671906

Showing the first eight; more decompositions exist.
