Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988980, here are decompositions:

17 + 988963 = 988980
29 + 988951 = 988980
43 + 988937 = 988980
71 + 988909 = 988980
79 + 988901 = 988980
103 + 988877 = 988980
131 + 988849 = 988980
151 + 988829 = 988980

Showing the first eight; more decompositions exist.
