Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725398, here are decompositions:

7 + 8725391 = 8725398
37 + 8725361 = 8725398
41 + 8725357 = 8725398
79 + 8725319 = 8725398
179 + 8725219 = 8725398
181 + 8725217 = 8725398
191 + 8725207 = 8725398
239 + 8725159 = 8725398

Showing the first eight; more decompositions exist.
