Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494018, here are decompositions:

79 + 493939 = 494018
211 + 493807 = 494018
241 + 493777 = 494018
271 + 493747 = 494018
307 + 493711 = 494018
397 + 493621 = 494018
439 + 493579 = 494018
487 + 493531 = 494018

Showing the first eight; more decompositions exist.
