Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691532, here are decompositions:

23 + 8691509 = 8691532
53 + 8691479 = 8691532
149 + 8691383 = 8691532
173 + 8691359 = 8691532
233 + 8691299 = 8691532
251 + 8691281 = 8691532
263 + 8691269 = 8691532
281 + 8691251 = 8691532

Showing the first eight; more decompositions exist.
