Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492280, here are decompositions:

23 + 492257 = 492280
29 + 492251 = 492280
53 + 492227 = 492280
167 + 492113 = 492280
197 + 492083 = 492280
227 + 492053 = 492280
233 + 492047 = 492280
251 + 492029 = 492280

Showing the first eight; more decompositions exist.
