Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725224, here are decompositions:

5 + 8725219 = 8725224
7 + 8725217 = 8725224
17 + 8725207 = 8725224
41 + 8725183 = 8725224
47 + 8725177 = 8725224
71 + 8725153 = 8725224
83 + 8725141 = 8725224
113 + 8725111 = 8725224

Showing the first eight; more decompositions exist.
