Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691550, here are decompositions:

41 + 8691509 = 8691550
53 + 8691497 = 8691550
71 + 8691479 = 8691550
137 + 8691413 = 8691550
167 + 8691383 = 8691550
191 + 8691359 = 8691550
251 + 8691299 = 8691550
269 + 8691281 = 8691550

Showing the first eight; more decompositions exist.
