Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691636, here are decompositions:

13 + 8691623 = 8691636
43 + 8691593 = 8691636
47 + 8691589 = 8691636
53 + 8691583 = 8691636
127 + 8691509 = 8691636
139 + 8691497 = 8691636
157 + 8691479 = 8691636
167 + 8691469 = 8691636

Showing the first eight; more decompositions exist.
