Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490436, here are decompositions:

19 + 490417 = 490436
43 + 490393 = 490436
97 + 490339 = 490436
127 + 490309 = 490436
229 + 490207 = 490436
277 + 490159 = 490436
379 + 490057 = 490436
433 + 490003 = 490436

Showing the first eight; more decompositions exist.
