Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997100, here are decompositions:

3 + 997097 = 997100
19 + 997081 = 997100
31 + 997069 = 997100
43 + 997057 = 997100
79 + 997021 = 997100
127 + 996973 = 997100
229 + 996871 = 997100
241 + 996859 = 997100

Showing the first eight; more decompositions exist.
