Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661170, here are decompositions:

109 + 8661061 = 8661170
127 + 8661043 = 8661170
223 + 8660947 = 8661170
241 + 8660929 = 8661170
283 + 8660887 = 8661170
307 + 8660863 = 8661170
373 + 8660797 = 8661170
487 + 8660683 = 8661170

Showing the first eight; more decompositions exist.
