Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021654, here are decompositions:

3 + 1021651 = 1021654
83 + 1021571 = 1021654
113 + 1021541 = 1021654
167 + 1021487 = 1021654
191 + 1021463 = 1021654
197 + 1021457 = 1021654
251 + 1021403 = 1021654
281 + 1021373 = 1021654

Showing the first eight; more decompositions exist.
