Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691426, here are decompositions:

13 + 8691413 = 8691426
19 + 8691407 = 8691426
43 + 8691383 = 8691426
53 + 8691373 = 8691426
59 + 8691367 = 8691426
67 + 8691359 = 8691426
113 + 8691313 = 8691426
127 + 8691299 = 8691426

Showing the first eight; more decompositions exist.
