Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021112, here are decompositions:

19 + 1021093 = 1021112
31 + 1021081 = 1021112
139 + 1020973 = 1021112
151 + 1020961 = 1021112
181 + 1020931 = 1021112
199 + 1020913 = 1021112
271 + 1020841 = 1021112
523 + 1020589 = 1021112

Showing the first eight; more decompositions exist.
