Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492288, here are decompositions:

7 + 492281 = 492288
31 + 492257 = 492288
37 + 492251 = 492288
61 + 492227 = 492288
211 + 492077 = 492288
227 + 492061 = 492288
229 + 492059 = 492288
241 + 492047 = 492288

Showing the first eight; more decompositions exist.
