Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725230, here are decompositions:

11 + 8725219 = 8725230
13 + 8725217 = 8725230
23 + 8725207 = 8725230
47 + 8725183 = 8725230
53 + 8725177 = 8725230
71 + 8725159 = 8725230
83 + 8725147 = 8725230
89 + 8725141 = 8725230

Showing the first eight; more decompositions exist.
