Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494666, here are decompositions:

19 + 494647 = 494666
79 + 494587 = 494666
103 + 494563 = 494666
127 + 494539 = 494666
223 + 494443 = 494666
283 + 494383 = 494666
307 + 494359 = 494666
313 + 494353 = 494666

Showing the first eight; more decompositions exist.
