Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725506, here are decompositions:

7 + 8725499 = 8725506
17 + 8725489 = 8725506
43 + 8725463 = 8725506
47 + 8725459 = 8725506
107 + 8725399 = 8725506
109 + 8725397 = 8725506
149 + 8725357 = 8725506
199 + 8725307 = 8725506

Showing the first eight; more decompositions exist.
