Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722356, here are decompositions:

17 + 8722339 = 8722356
23 + 8722333 = 8722356
53 + 8722303 = 8722356
59 + 8722297 = 8722356
73 + 8722283 = 8722356
163 + 8722193 = 8722356
233 + 8722123 = 8722356
239 + 8722117 = 8722356

Showing the first eight; more decompositions exist.
