Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706320, here are decompositions:

31 + 8706289 = 8706320
37 + 8706283 = 8706320
43 + 8706277 = 8706320
79 + 8706241 = 8706320
151 + 8706169 = 8706320
157 + 8706163 = 8706320
241 + 8706079 = 8706320
307 + 8706013 = 8706320

Showing the first eight; more decompositions exist.
