Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494030, here are decompositions:

7 + 494023 = 494030
37 + 493993 = 494030
157 + 493873 = 494030
223 + 493807 = 494030
283 + 493747 = 494030
337 + 493693 = 494030
373 + 493657 = 494030
409 + 493621 = 494030

Showing the first eight; more decompositions exist.
