Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021756, here are decompositions:

3 + 1021753 = 1021756
59 + 1021697 = 1021756
83 + 1021673 = 1021756
179 + 1021577 = 1021756
269 + 1021487 = 1021756
293 + 1021463 = 1021756
353 + 1021403 = 1021756
383 + 1021373 = 1021756

Showing the first eight; more decompositions exist.
