Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725540, here are decompositions:

17 + 8725523 = 8725540
29 + 8725511 = 8725540
41 + 8725499 = 8725540
59 + 8725481 = 8725540
149 + 8725391 = 8725540
179 + 8725361 = 8725540
233 + 8725307 = 8725540
401 + 8725139 = 8725540

Showing the first eight; more decompositions exist.
