Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725680, here are decompositions:

11 + 8725669 = 8725680
23 + 8725657 = 8725680
37 + 8725643 = 8725680
53 + 8725627 = 8725680
59 + 8725621 = 8725680
71 + 8725609 = 8725680
109 + 8725571 = 8725680
113 + 8725567 = 8725680

Showing the first eight; more decompositions exist.
