Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998490, here are decompositions:

19 + 998471 = 998490
47 + 998443 = 998490
61 + 998429 = 998490
67 + 998423 = 998490
71 + 998419 = 998490
79 + 998411 = 998490
109 + 998381 = 998490
113 + 998377 = 998490

Showing the first eight; more decompositions exist.
