Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492788, here are decompositions:

7 + 492781 = 492788
19 + 492769 = 492788
31 + 492757 = 492788
67 + 492721 = 492788
157 + 492631 = 492788
277 + 492511 = 492788
367 + 492421 = 492788
379 + 492409 = 492788

Showing the first eight; more decompositions exist.
