Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492686, here are decompositions:

13 + 492673 = 492686
67 + 492619 = 492686
163 + 492523 = 492686
199 + 492487 = 492686
223 + 492463 = 492686
277 + 492409 = 492686
283 + 492403 = 492686
367 + 492319 = 492686

Showing the first eight; more decompositions exist.
