Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691480, here are decompositions:

11 + 8691469 = 8691480
29 + 8691451 = 8691480
47 + 8691433 = 8691480
67 + 8691413 = 8691480
73 + 8691407 = 8691480
89 + 8691391 = 8691480
97 + 8691383 = 8691480
107 + 8691373 = 8691480

Showing the first eight; more decompositions exist.
