Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684426, here are decompositions:

7 + 8684419 = 8684426
19 + 8684407 = 8684426
67 + 8684359 = 8684426
97 + 8684329 = 8684426
337 + 8684089 = 8684426
349 + 8684077 = 8684426
379 + 8684047 = 8684426
397 + 8684029 = 8684426

Showing the first eight; more decompositions exist.
