Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1004998, here are decompositions:

11 + 1004987 = 1004998
17 + 1004981 = 1004998
251 + 1004747 = 1004998
311 + 1004687 = 1004998
347 + 1004651 = 1004998
431 + 1004567 = 1004998
461 + 1004537 = 1004998
521 + 1004477 = 1004998

Showing the first eight; more decompositions exist.
