Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494490, here are decompositions:

19 + 494471 = 494490
47 + 494443 = 494490
83 + 494407 = 494490
103 + 494387 = 494490
107 + 494383 = 494490
109 + 494381 = 494490
131 + 494359 = 494490
137 + 494353 = 494490

Showing the first eight; more decompositions exist.
