Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021366, here are decompositions:

83 + 1021283 = 1021366
107 + 1021259 = 1021366
113 + 1021253 = 1021366
149 + 1021217 = 1021366
167 + 1021199 = 1021366
239 + 1021127 = 1021366
293 + 1021073 = 1021366
347 + 1021019 = 1021366

Showing the first eight; more decompositions exist.
