Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691676, here are decompositions:

3 + 8691673 = 8691676
23 + 8691653 = 8691676
53 + 8691623 = 8691676
83 + 8691593 = 8691676
89 + 8691587 = 8691676
167 + 8691509 = 8691676
179 + 8691497 = 8691676
197 + 8691479 = 8691676

Showing the first eight; more decompositions exist.
