Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8599428, here are decompositions:

17 + 8599411 = 8599428
31 + 8599397 = 8599428
109 + 8599319 = 8599428
127 + 8599301 = 8599428
139 + 8599289 = 8599428
157 + 8599271 = 8599428
269 + 8599159 = 8599428
311 + 8599117 = 8599428

Showing the first eight; more decompositions exist.
