Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725510, here are decompositions:

11 + 8725499 = 8725510
29 + 8725481 = 8725510
47 + 8725463 = 8725510
89 + 8725421 = 8725510
113 + 8725397 = 8725510
149 + 8725361 = 8725510
191 + 8725319 = 8725510
257 + 8725253 = 8725510

Showing the first eight; more decompositions exist.
