Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494000, here are decompositions:

7 + 493993 = 494000
61 + 493939 = 494000
103 + 493897 = 494000
127 + 493873 = 494000
193 + 493807 = 494000
223 + 493777 = 494000
271 + 493729 = 494000
307 + 493693 = 494000

Showing the first eight; more decompositions exist.
