Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492986, here are decompositions:

7 + 492979 = 492986
19 + 492967 = 492986
103 + 492883 = 492986
223 + 492763 = 492986
229 + 492757 = 492986
313 + 492673 = 492986
367 + 492619 = 492986
463 + 492523 = 492986

Showing the first eight; more decompositions exist.
