Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670320, here are decompositions:

7 + 8670313 = 8670320
19 + 8670301 = 8670320
163 + 8670157 = 8670320
193 + 8670127 = 8670320
283 + 8670037 = 8670320
313 + 8670007 = 8670320
331 + 8669989 = 8670320
397 + 8669923 = 8670320

Showing the first eight; more decompositions exist.
