Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691508, here are decompositions:

11 + 8691497 = 8691508
29 + 8691479 = 8691508
101 + 8691407 = 8691508
149 + 8691359 = 8691508
227 + 8691281 = 8691508
239 + 8691269 = 8691508
257 + 8691251 = 8691508
269 + 8691239 = 8691508

Showing the first eight; more decompositions exist.
