Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725668, here are decompositions:

11 + 8725657 = 8725668
37 + 8725631 = 8725668
41 + 8725627 = 8725668
47 + 8725621 = 8725668
59 + 8725609 = 8725668
97 + 8725571 = 8725668
101 + 8725567 = 8725668
137 + 8725531 = 8725668

Showing the first eight; more decompositions exist.
