Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998980, here are decompositions:

11 + 998969 = 998980
23 + 998957 = 998980
29 + 998951 = 998980
53 + 998927 = 998980
71 + 998909 = 998980
83 + 998897 = 998980
137 + 998843 = 998980
149 + 998831 = 998980

Showing the first eight; more decompositions exist.
