Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492990, here are decompositions:

11 + 492979 = 492990
23 + 492967 = 492990
79 + 492911 = 492990
89 + 492901 = 492990
97 + 492893 = 492990
107 + 492883 = 492990
137 + 492853 = 492990
151 + 492839 = 492990

Showing the first eight; more decompositions exist.
