Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708320, here are decompositions:

29 + 8708291 = 8708320
59 + 8708261 = 8708320
167 + 8708153 = 8708320
191 + 8708129 = 8708320
227 + 8708093 = 8708320
233 + 8708087 = 8708320
239 + 8708081 = 8708320
251 + 8708069 = 8708320

Showing the first eight; more decompositions exist.
