Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691538, here are decompositions:

29 + 8691509 = 8691538
41 + 8691497 = 8691538
59 + 8691479 = 8691538
131 + 8691407 = 8691538
179 + 8691359 = 8691538
239 + 8691299 = 8691538
257 + 8691281 = 8691538
269 + 8691269 = 8691538

Showing the first eight; more decompositions exist.
