Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021922, here are decompositions:

3 + 1021919 = 1021922
43 + 1021879 = 1021922
61 + 1021861 = 1021922
73 + 1021849 = 1021922
163 + 1021759 = 1021922
211 + 1021711 = 1021922
271 + 1021651 = 1021922
439 + 1021483 = 1021922

Showing the first eight; more decompositions exist.
