Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656906, here are decompositions:

3 + 8656903 = 8656906
59 + 8656847 = 8656906
173 + 8656733 = 8656906
179 + 8656727 = 8656906
239 + 8656667 = 8656906
317 + 8656589 = 8656906
359 + 8656547 = 8656906
383 + 8656523 = 8656906

Showing the first eight; more decompositions exist.
