Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998938, here are decompositions:

11 + 998927 = 998938
29 + 998909 = 998938
41 + 998897 = 998938
107 + 998831 = 998938
179 + 998759 = 998938
251 + 998687 = 998938
257 + 998681 = 998938
401 + 998537 = 998938

Showing the first eight; more decompositions exist.
