Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 982188, here are decompositions:

5 + 982183 = 982188
17 + 982171 = 982188
37 + 982151 = 982188
41 + 982147 = 982188
71 + 982117 = 982188
89 + 982099 = 982188
101 + 982087 = 982188
127 + 982061 = 982188

Showing the first eight; more decompositions exist.
