Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998628, here are decompositions:

5 + 998623 = 998628
11 + 998617 = 998628
67 + 998561 = 998628
89 + 998539 = 998628
101 + 998527 = 998628
131 + 998497 = 998628
157 + 998471 = 998628
199 + 998429 = 998628

Showing the first eight; more decompositions exist.
