Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670744, here are decompositions:

31 + 8670713 = 8670744
41 + 8670703 = 8670744
107 + 8670637 = 8670744
191 + 8670553 = 8670744
193 + 8670551 = 8670744
211 + 8670533 = 8670744
241 + 8670503 = 8670744
263 + 8670481 = 8670744

Showing the first eight; more decompositions exist.
