Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 982142, here are decompositions:

43 + 982099 = 982142
79 + 982063 = 982142
163 + 981979 = 982142
181 + 981961 = 982142
193 + 981949 = 982142
223 + 981919 = 982142
229 + 981913 = 982142
331 + 981811 = 982142

Showing the first eight; more decompositions exist.
