Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691136, here are decompositions:

17 + 8691119 = 8691136
173 + 8690963 = 8691136
269 + 8690867 = 8691136
347 + 8690789 = 8691136
353 + 8690783 = 8691136
569 + 8690567 = 8691136
647 + 8690489 = 8691136
659 + 8690477 = 8691136

Showing the first eight; more decompositions exist.
