Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725524, here are decompositions:

13 + 8725511 = 8725524
43 + 8725481 = 8725524
61 + 8725463 = 8725524
103 + 8725421 = 8725524
127 + 8725397 = 8725524
163 + 8725361 = 8725524
167 + 8725357 = 8725524
271 + 8725253 = 8725524

Showing the first eight; more decompositions exist.
