Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490526, here are decompositions:

7 + 490519 = 490526
67 + 490459 = 490526
73 + 490453 = 490526
109 + 490417 = 490526
277 + 490249 = 490526
367 + 490159 = 490526
409 + 490117 = 490526
523 + 490003 = 490526

Showing the first eight; more decompositions exist.
