Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492540, here are decompositions:

17 + 492523 = 492540
29 + 492511 = 492540
53 + 492487 = 492540
73 + 492467 = 492540
109 + 492431 = 492540
127 + 492413 = 492540
131 + 492409 = 492540
137 + 492403 = 492540

Showing the first eight; more decompositions exist.
