Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981176, here are decompositions:

3 + 981173 = 981176
37 + 981139 = 981176
43 + 981133 = 981176
103 + 981073 = 981176
109 + 981067 = 981176
127 + 981049 = 981176
139 + 981037 = 981176
277 + 980899 = 981176

Showing the first eight; more decompositions exist.
