Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998940, here are decompositions:

13 + 998927 = 998940
23 + 998917 = 998940
31 + 998909 = 998940
43 + 998897 = 998940
79 + 998861 = 998940
83 + 998857 = 998940
97 + 998843 = 998940
101 + 998839 = 998940

Showing the first eight; more decompositions exist.
