Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709320, here are decompositions:

3 + 8709317 = 8709320
7 + 8709313 = 8709320
19 + 8709301 = 8709320
31 + 8709289 = 8709320
181 + 8709139 = 8709320
199 + 8709121 = 8709320
241 + 8709079 = 8709320
313 + 8709007 = 8709320

Showing the first eight; more decompositions exist.
