Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 969138, here are decompositions:

7 + 969131 = 969138
29 + 969109 = 969138
41 + 969097 = 969138
67 + 969071 = 969138
89 + 969049 = 969138
97 + 969041 = 969138
101 + 969037 = 969138
127 + 969011 = 969138

Showing the first eight; more decompositions exist.
