Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709408, here are decompositions:

31 + 8709377 = 8709408
47 + 8709361 = 8709408
107 + 8709301 = 8709408
109 + 8709299 = 8709408
137 + 8709271 = 8709408
151 + 8709257 = 8709408
179 + 8709229 = 8709408
269 + 8709139 = 8709408

Showing the first eight; more decompositions exist.
