Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492808, here are decompositions:

47 + 492761 = 492808
89 + 492719 = 492808
101 + 492707 = 492808
137 + 492671 = 492808
149 + 492659 = 492808
167 + 492641 = 492808
179 + 492629 = 492808
191 + 492617 = 492808

Showing the first eight; more decompositions exist.
