Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725530, here are decompositions:

7 + 8725523 = 8725530
19 + 8725511 = 8725530
31 + 8725499 = 8725530
41 + 8725489 = 8725530
67 + 8725463 = 8725530
71 + 8725459 = 8725530
101 + 8725429 = 8725530
109 + 8725421 = 8725530

Showing the first eight; more decompositions exist.
