Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725566, here are decompositions:

19 + 8725547 = 8725566
43 + 8725523 = 8725566
67 + 8725499 = 8725566
103 + 8725463 = 8725566
107 + 8725459 = 8725566
137 + 8725429 = 8725566
167 + 8725399 = 8725566
313 + 8725253 = 8725566

Showing the first eight; more decompositions exist.
