Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998968, here are decompositions:

11 + 998957 = 998968
17 + 998951 = 998968
41 + 998927 = 998968
59 + 998909 = 998968
71 + 998897 = 998968
107 + 998861 = 998968
137 + 998831 = 998968
149 + 998819 = 998968

Showing the first eight; more decompositions exist.
