Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021288, here are decompositions:

5 + 1021283 = 1021288
17 + 1021271 = 1021288
29 + 1021259 = 1021288
71 + 1021217 = 1021288
89 + 1021199 = 1021288
131 + 1021157 = 1021288
197 + 1021091 = 1021288
269 + 1021019 = 1021288

Showing the first eight; more decompositions exist.
