Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691732, here are decompositions:

43 + 8691689 = 8691732
59 + 8691673 = 8691732
79 + 8691653 = 8691732
89 + 8691643 = 8691732
109 + 8691623 = 8691732
139 + 8691593 = 8691732
149 + 8691583 = 8691732
151 + 8691581 = 8691732

Showing the first eight; more decompositions exist.
