Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725656, here are decompositions:

13 + 8725643 = 8725656
29 + 8725627 = 8725656
47 + 8725609 = 8725656
89 + 8725567 = 8725656
109 + 8725547 = 8725656
157 + 8725499 = 8725656
167 + 8725489 = 8725656
193 + 8725463 = 8725656

Showing the first eight; more decompositions exist.
