Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492538, here are decompositions:

47 + 492491 = 492538
71 + 492467 = 492538
107 + 492431 = 492538
149 + 492389 = 492538
239 + 492299 = 492538
257 + 492281 = 492538
281 + 492257 = 492538
311 + 492227 = 492538

Showing the first eight; more decompositions exist.
