Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725422, here are decompositions:

23 + 8725399 = 8725422
31 + 8725391 = 8725422
59 + 8725363 = 8725422
61 + 8725361 = 8725422
103 + 8725319 = 8725422
179 + 8725243 = 8725422
239 + 8725183 = 8725422
263 + 8725159 = 8725422

Showing the first eight; more decompositions exist.
