Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492238, here are decompositions:

11 + 492227 = 492238
179 + 492059 = 492238
191 + 492047 = 492238
269 + 491969 = 492238
401 + 491837 = 492238
419 + 491819 = 492238
449 + 491789 = 492238
491 + 491747 = 492238

Showing the first eight; more decompositions exist.
