Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722316, here are decompositions:

13 + 8722303 = 8722316
19 + 8722297 = 8722316
79 + 8722237 = 8722316
193 + 8722123 = 8722316
199 + 8722117 = 8722316
223 + 8722093 = 8722316
283 + 8722033 = 8722316
307 + 8722009 = 8722316

Showing the first eight; more decompositions exist.
