Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725470, here are decompositions:

7 + 8725463 = 8725470
11 + 8725459 = 8725470
41 + 8725429 = 8725470
71 + 8725399 = 8725470
73 + 8725397 = 8725470
79 + 8725391 = 8725470
107 + 8725363 = 8725470
109 + 8725361 = 8725470

Showing the first eight; more decompositions exist.
