Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691740, here are decompositions:

7 + 8691733 = 8691740
67 + 8691673 = 8691740
73 + 8691667 = 8691740
97 + 8691643 = 8691740
151 + 8691589 = 8691740
157 + 8691583 = 8691740
199 + 8691541 = 8691740
271 + 8691469 = 8691740

Showing the first eight; more decompositions exist.
