Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725564, here are decompositions:

17 + 8725547 = 8725564
41 + 8725523 = 8725564
53 + 8725511 = 8725564
83 + 8725481 = 8725564
101 + 8725463 = 8725564
167 + 8725397 = 8725564
173 + 8725391 = 8725564
257 + 8725307 = 8725564

Showing the first eight; more decompositions exist.
