Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 982178, here are decompositions:

7 + 982171 = 982178
31 + 982147 = 982178
61 + 982117 = 982178
79 + 982099 = 982178
157 + 982021 = 982178
199 + 981979 = 982178
229 + 981949 = 982178
367 + 981811 = 982178

Showing the first eight; more decompositions exist.
