Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981162, here are decompositions:

11 + 981151 = 981162
23 + 981139 = 981162
29 + 981133 = 981162
71 + 981091 = 981162
89 + 981073 = 981162
101 + 981061 = 981162
113 + 981049 = 981162
139 + 981023 = 981162

Showing the first eight; more decompositions exist.
