Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691330, here are decompositions:

17 + 8691313 = 8691330
31 + 8691299 = 8691330
61 + 8691269 = 8691330
79 + 8691251 = 8691330
83 + 8691247 = 8691330
101 + 8691229 = 8691330
107 + 8691223 = 8691330
163 + 8691167 = 8691330

Showing the first eight; more decompositions exist.
