Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725688, here are decompositions:

7 + 8725681 = 8725688
19 + 8725669 = 8725688
31 + 8725657 = 8725688
61 + 8725627 = 8725688
67 + 8725621 = 8725688
79 + 8725609 = 8725688
157 + 8725531 = 8725688
199 + 8725489 = 8725688

Showing the first eight; more decompositions exist.
