Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691744, here are decompositions:

11 + 8691733 = 8691744
13 + 8691731 = 8691744
71 + 8691673 = 8691744
101 + 8691643 = 8691744
151 + 8691593 = 8691744
157 + 8691587 = 8691744
163 + 8691581 = 8691744
263 + 8691481 = 8691744

Showing the first eight; more decompositions exist.
