Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691400, here are decompositions:

17 + 8691383 = 8691400
41 + 8691359 = 8691400
101 + 8691299 = 8691400
131 + 8691269 = 8691400
149 + 8691251 = 8691400
191 + 8691209 = 8691400
233 + 8691167 = 8691400
281 + 8691119 = 8691400

Showing the first eight; more decompositions exist.
