Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670906, here are decompositions:

19 + 8670887 = 8670906
37 + 8670869 = 8670906
43 + 8670863 = 8670906
163 + 8670743 = 8670906
193 + 8670713 = 8670906
197 + 8670709 = 8670906
227 + 8670679 = 8670906
239 + 8670667 = 8670906

Showing the first eight; more decompositions exist.
