Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691224, here are decompositions:

13 + 8691211 = 8691224
37 + 8691187 = 8691224
67 + 8691157 = 8691224
97 + 8691127 = 8691224
181 + 8691043 = 8691224
271 + 8690953 = 8691224
277 + 8690947 = 8691224
307 + 8690917 = 8691224

Showing the first eight; more decompositions exist.
