Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647906, here are decompositions:

17 + 8647889 = 8647906
83 + 8647823 = 8647906
89 + 8647817 = 8647906
167 + 8647739 = 8647906
317 + 8647589 = 8647906
557 + 8647349 = 8647906
653 + 8647253 = 8647906
677 + 8647229 = 8647906

Showing the first eight; more decompositions exist.
