Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021270, here are decompositions:

11 + 1021259 = 1021270
17 + 1021253 = 1021270
53 + 1021217 = 1021270
71 + 1021199 = 1021270
113 + 1021157 = 1021270
179 + 1021091 = 1021270
197 + 1021073 = 1021270
227 + 1021043 = 1021270

Showing the first eight; more decompositions exist.
