Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725570, here are decompositions:

3 + 8725567 = 8725570
23 + 8725547 = 8725570
47 + 8725523 = 8725570
59 + 8725511 = 8725570
71 + 8725499 = 8725570
89 + 8725481 = 8725570
107 + 8725463 = 8725570
149 + 8725421 = 8725570

Showing the first eight; more decompositions exist.
