Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8759128, here are decompositions:

5 + 8759123 = 8759128
41 + 8759087 = 8759128
89 + 8759039 = 8759128
149 + 8758979 = 8759128
197 + 8758931 = 8759128
227 + 8758901 = 8759128
239 + 8758889 = 8759128
251 + 8758877 = 8759128

Showing the first eight; more decompositions exist.
