Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021408, here are decompositions:

5 + 1021403 = 1021408
41 + 1021367 = 1021408
107 + 1021301 = 1021408
137 + 1021271 = 1021408
149 + 1021259 = 1021408
191 + 1021217 = 1021408
251 + 1021157 = 1021408
281 + 1021127 = 1021408

Showing the first eight; more decompositions exist.
