Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492158, here are decompositions:

97 + 492061 = 492158
151 + 492007 = 492158
181 + 491977 = 492158
307 + 491851 = 492158
421 + 491737 = 492158
439 + 491719 = 492158
547 + 491611 = 492158
577 + 491581 = 492158

Showing the first eight; more decompositions exist.
