Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660906, here are decompositions:

19 + 8660887 = 8660906
43 + 8660863 = 8660906
109 + 8660797 = 8660906
139 + 8660767 = 8660906
223 + 8660683 = 8660906
283 + 8660623 = 8660906
337 + 8660569 = 8660906
367 + 8660539 = 8660906

Showing the first eight; more decompositions exist.
