Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494530, here are decompositions:

11 + 494519 = 494530
59 + 494471 = 494530
89 + 494441 = 494530
149 + 494381 = 494530
263 + 494267 = 494530
293 + 494237 = 494530
317 + 494213 = 494530
383 + 494147 = 494530

Showing the first eight; more decompositions exist.
