Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492188, here are decompositions:

127 + 492061 = 492188
181 + 492007 = 492188
211 + 491977 = 492188
331 + 491857 = 492188
337 + 491851 = 492188
457 + 491731 = 492188
577 + 491611 = 492188
607 + 491581 = 492188

Showing the first eight; more decompositions exist.
