Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494558, here are decompositions:

19 + 494539 = 494558
37 + 494521 = 494558
61 + 494497 = 494558
151 + 494407 = 494558
199 + 494359 = 494558
241 + 494317 = 494558
271 + 494287 = 494558
277 + 494281 = 494558

Showing the first eight; more decompositions exist.
