Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8686906, here are decompositions:

5 + 8686901 = 8686906
17 + 8686889 = 8686906
23 + 8686883 = 8686906
29 + 8686877 = 8686906
227 + 8686679 = 8686906
317 + 8686589 = 8686906
419 + 8686487 = 8686906
443 + 8686463 = 8686906

Showing the first eight; more decompositions exist.
