Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021480, here are decompositions:

17 + 1021463 = 1021480
23 + 1021457 = 1021480
107 + 1021373 = 1021480
113 + 1021367 = 1021480
149 + 1021331 = 1021480
179 + 1021301 = 1021480
191 + 1021289 = 1021480
197 + 1021283 = 1021480

Showing the first eight; more decompositions exist.
