Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725536, here are decompositions:

5 + 8725531 = 8725536
13 + 8725523 = 8725536
37 + 8725499 = 8725536
47 + 8725489 = 8725536
73 + 8725463 = 8725536
107 + 8725429 = 8725536
137 + 8725399 = 8725536
139 + 8725397 = 8725536

Showing the first eight; more decompositions exist.
