Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691486, here are decompositions:

5 + 8691481 = 8691486
7 + 8691479 = 8691486
17 + 8691469 = 8691486
53 + 8691433 = 8691486
73 + 8691413 = 8691486
79 + 8691407 = 8691486
103 + 8691383 = 8691486
113 + 8691373 = 8691486

Showing the first eight; more decompositions exist.
