Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492940, here are decompositions:

29 + 492911 = 492940
47 + 492893 = 492940
101 + 492839 = 492940
179 + 492761 = 492940
233 + 492707 = 492940
269 + 492671 = 492940
281 + 492659 = 492940
293 + 492647 = 492940

Showing the first eight; more decompositions exist.
