Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690806, here are decompositions:

17 + 8690789 = 8690806
23 + 8690783 = 8690806
167 + 8690639 = 8690806
239 + 8690567 = 8690806
317 + 8690489 = 8690806
353 + 8690453 = 8690806
419 + 8690387 = 8690806
503 + 8690303 = 8690806

Showing the first eight; more decompositions exist.
