Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725808, here are decompositions:

109 + 8725699 = 8725808
127 + 8725681 = 8725808
139 + 8725669 = 8725808
151 + 8725657 = 8725808
181 + 8725627 = 8725808
199 + 8725609 = 8725808
241 + 8725567 = 8725808
277 + 8725531 = 8725808

Showing the first eight; more decompositions exist.
