Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021696, here are decompositions:

23 + 1021673 = 1021696
233 + 1021463 = 1021696
239 + 1021457 = 1021696
293 + 1021403 = 1021696
443 + 1021253 = 1021696
479 + 1021217 = 1021696
569 + 1021127 = 1021696
653 + 1021043 = 1021696

Showing the first eight; more decompositions exist.
