Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725522, here are decompositions:

11 + 8725511 = 8725522
23 + 8725499 = 8725522
41 + 8725481 = 8725522
59 + 8725463 = 8725522
101 + 8725421 = 8725522
131 + 8725391 = 8725522
269 + 8725253 = 8725522
383 + 8725139 = 8725522

Showing the first eight; more decompositions exist.
