Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725528, here are decompositions:

5 + 8725523 = 8725528
17 + 8725511 = 8725528
29 + 8725499 = 8725528
47 + 8725481 = 8725528
107 + 8725421 = 8725528
131 + 8725397 = 8725528
137 + 8725391 = 8725528
167 + 8725361 = 8725528

Showing the first eight; more decompositions exist.
