Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492790, here are decompositions:

29 + 492761 = 492790
59 + 492731 = 492790
71 + 492719 = 492790
83 + 492707 = 492790
131 + 492659 = 492790
149 + 492641 = 492790
173 + 492617 = 492790
227 + 492563 = 492790

Showing the first eight; more decompositions exist.
