Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670888, here are decompositions:

19 + 8670869 = 8670888
97 + 8670791 = 8670888
137 + 8670751 = 8670888
179 + 8670709 = 8670888
251 + 8670637 = 8670888
269 + 8670619 = 8670888
277 + 8670611 = 8670888
337 + 8670551 = 8670888

Showing the first eight; more decompositions exist.
