Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725548, here are decompositions:

17 + 8725531 = 8725548
37 + 8725511 = 8725548
59 + 8725489 = 8725548
67 + 8725481 = 8725548
89 + 8725459 = 8725548
127 + 8725421 = 8725548
149 + 8725399 = 8725548
151 + 8725397 = 8725548

Showing the first eight; more decompositions exist.
