Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691510, here are decompositions:

13 + 8691497 = 8691510
29 + 8691481 = 8691510
31 + 8691479 = 8691510
41 + 8691469 = 8691510
59 + 8691451 = 8691510
97 + 8691413 = 8691510
103 + 8691407 = 8691510
127 + 8691383 = 8691510

Showing the first eight; more decompositions exist.
