Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691436, here are decompositions:

3 + 8691433 = 8691436
23 + 8691413 = 8691436
29 + 8691407 = 8691436
53 + 8691383 = 8691436
137 + 8691299 = 8691436
167 + 8691269 = 8691436
197 + 8691239 = 8691436
227 + 8691209 = 8691436

Showing the first eight; more decompositions exist.
