Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 982172, here are decompositions:

73 + 982099 = 982172
109 + 982063 = 982172
151 + 982021 = 982172
193 + 981979 = 982172
211 + 981961 = 982172
223 + 981949 = 982172
283 + 981889 = 982172
349 + 981823 = 982172

Showing the first eight; more decompositions exist.
