Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998740, here are decompositions:

3 + 998737 = 998740
23 + 998717 = 998740
53 + 998687 = 998740
59 + 998681 = 998740
89 + 998651 = 998740
107 + 998633 = 998740
179 + 998561 = 998740
227 + 998513 = 998740

Showing the first eight; more decompositions exist.
