Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722358, here are decompositions:

19 + 8722339 = 8722358
61 + 8722297 = 8722358
67 + 8722291 = 8722358
241 + 8722117 = 8722358
277 + 8722081 = 8722358
331 + 8722027 = 8722358
349 + 8722009 = 8722358
691 + 8721667 = 8722358

Showing the first eight; more decompositions exist.
