Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645786, here are decompositions:

13 + 8645773 = 8645786
67 + 8645719 = 8645786
139 + 8645647 = 8645786
199 + 8645587 = 8645786
337 + 8645449 = 8645786
379 + 8645407 = 8645786
433 + 8645353 = 8645786
547 + 8645239 = 8645786

Showing the first eight; more decompositions exist.
