Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021468, here are decompositions:

5 + 1021463 = 1021468
11 + 1021457 = 1021468
101 + 1021367 = 1021468
137 + 1021331 = 1021468
167 + 1021301 = 1021468
179 + 1021289 = 1021468
197 + 1021271 = 1021468
251 + 1021217 = 1021468

Showing the first eight; more decompositions exist.
