Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691748, here are decompositions:

17 + 8691731 = 8691748
59 + 8691689 = 8691748
167 + 8691581 = 8691748
239 + 8691509 = 8691748
251 + 8691497 = 8691748
269 + 8691479 = 8691748
389 + 8691359 = 8691748
449 + 8691299 = 8691748

Showing the first eight; more decompositions exist.
