Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725370, here are decompositions:

7 + 8725363 = 8725370
13 + 8725357 = 8725370
127 + 8725243 = 8725370
151 + 8725219 = 8725370
163 + 8725207 = 8725370
193 + 8725177 = 8725370
211 + 8725159 = 8725370
223 + 8725147 = 8725370

Showing the first eight; more decompositions exist.
