Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021582, here are decompositions:

5 + 1021577 = 1021582
11 + 1021571 = 1021582
41 + 1021541 = 1021582
179 + 1021403 = 1021582
251 + 1021331 = 1021582
281 + 1021301 = 1021582
293 + 1021289 = 1021582
311 + 1021271 = 1021582

Showing the first eight; more decompositions exist.
