Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725266, here are decompositions:

13 + 8725253 = 8725266
23 + 8725243 = 8725266
47 + 8725219 = 8725266
59 + 8725207 = 8725266
83 + 8725183 = 8725266
89 + 8725177 = 8725266
107 + 8725159 = 8725266
113 + 8725153 = 8725266

Showing the first eight; more decompositions exist.
