Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668826, here are decompositions:

13 + 8668813 = 8668826
43 + 8668783 = 8668826
139 + 8668687 = 8668826
277 + 8668549 = 8668826
307 + 8668519 = 8668826
337 + 8668489 = 8668826
367 + 8668459 = 8668826
457 + 8668369 = 8668826

Showing the first eight; more decompositions exist.
