Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989072, here are decompositions:

13 + 989059 = 989072
43 + 989029 = 989072
61 + 989011 = 989072
109 + 988963 = 989072
163 + 988909 = 989072
211 + 988861 = 989072
223 + 988849 = 989072
283 + 988789 = 989072

Showing the first eight; more decompositions exist.
