Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989138, here are decompositions:

19 + 989119 = 989138
67 + 989071 = 989138
79 + 989059 = 989138
109 + 989029 = 989138
127 + 989011 = 989138
229 + 988909 = 989138
277 + 988861 = 989138
349 + 988789 = 989138

Showing the first eight; more decompositions exist.
