Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490538, here are decompositions:

19 + 490519 = 490538
79 + 490459 = 490538
199 + 490339 = 490538
229 + 490309 = 490538
271 + 490267 = 490538
331 + 490207 = 490538
337 + 490201 = 490538
379 + 490159 = 490538

Showing the first eight; more decompositions exist.
