Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725760, here are decompositions:

3 + 8725757 = 8725760
61 + 8725699 = 8725760
79 + 8725681 = 8725760
103 + 8725657 = 8725760
139 + 8725621 = 8725760
151 + 8725609 = 8725760
193 + 8725567 = 8725760
229 + 8725531 = 8725760

Showing the first eight; more decompositions exist.
