Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494540, here are decompositions:

19 + 494521 = 494540
43 + 494497 = 494540
97 + 494443 = 494540
127 + 494413 = 494540
157 + 494383 = 494540
181 + 494359 = 494540
199 + 494341 = 494540
223 + 494317 = 494540

Showing the first eight; more decompositions exist.
