Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 982100, here are decompositions:

3 + 982097 = 982100
13 + 982087 = 982100
37 + 982063 = 982100
43 + 982057 = 982100
79 + 982021 = 982100
139 + 981961 = 982100
151 + 981949 = 982100
181 + 981919 = 982100

Showing the first eight; more decompositions exist.
