Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989982, here are decompositions:

5 + 989977 = 989982
11 + 989971 = 989982
23 + 989959 = 989982
31 + 989951 = 989982
43 + 989939 = 989982
53 + 989929 = 989982
61 + 989921 = 989982
73 + 989909 = 989982

Showing the first eight; more decompositions exist.
