Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725788, here are decompositions:

31 + 8725757 = 8725788
89 + 8725699 = 8725788
107 + 8725681 = 8725788
131 + 8725657 = 8725788
157 + 8725631 = 8725788
167 + 8725621 = 8725788
179 + 8725609 = 8725788
241 + 8725547 = 8725788

Showing the first eight; more decompositions exist.
