Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490506, here are decompositions:

7 + 490499 = 490506
13 + 490493 = 490506
43 + 490463 = 490506
47 + 490459 = 490506
53 + 490453 = 490506
89 + 490417 = 490506
113 + 490393 = 490506
139 + 490367 = 490506

Showing the first eight; more decompositions exist.
