Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021684, here are decompositions:

11 + 1021673 = 1021684
23 + 1021661 = 1021684
107 + 1021577 = 1021684
113 + 1021571 = 1021684
197 + 1021487 = 1021684
227 + 1021457 = 1021684
281 + 1021403 = 1021684
311 + 1021373 = 1021684

Showing the first eight; more decompositions exist.
