Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492988, here are decompositions:

149 + 492839 = 492988
227 + 492761 = 492988
257 + 492731 = 492988
269 + 492719 = 492988
281 + 492707 = 492988
317 + 492671 = 492988
347 + 492641 = 492988
359 + 492629 = 492988

Showing the first eight; more decompositions exist.
