Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691312, here are decompositions:

13 + 8691299 = 8691312
31 + 8691281 = 8691312
43 + 8691269 = 8691312
61 + 8691251 = 8691312
73 + 8691239 = 8691312
83 + 8691229 = 8691312
89 + 8691223 = 8691312
101 + 8691211 = 8691312

Showing the first eight; more decompositions exist.
