Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492740, here are decompositions:

19 + 492721 = 492740
67 + 492673 = 492740
109 + 492631 = 492740
139 + 492601 = 492740
229 + 492511 = 492740
277 + 492463 = 492740
331 + 492409 = 492740
337 + 492403 = 492740

Showing the first eight; more decompositions exist.
