Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492478, here are decompositions:

11 + 492467 = 492478
47 + 492431 = 492478
89 + 492389 = 492478
101 + 492377 = 492478
179 + 492299 = 492478
197 + 492281 = 492478
227 + 492251 = 492478
251 + 492227 = 492478

Showing the first eight; more decompositions exist.
