Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492218, here are decompositions:

151 + 492067 = 492218
157 + 492061 = 492218
211 + 492007 = 492218
241 + 491977 = 492218
367 + 491851 = 492218
421 + 491797 = 492218
487 + 491731 = 492218
499 + 491719 = 492218

Showing the first eight; more decompositions exist.
