Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691700, here are decompositions:

11 + 8691689 = 8691700
47 + 8691653 = 8691700
107 + 8691593 = 8691700
113 + 8691587 = 8691700
191 + 8691509 = 8691700
293 + 8691407 = 8691700
317 + 8691383 = 8691700
401 + 8691299 = 8691700

Showing the first eight; more decompositions exist.
