Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021938, here are decompositions:

19 + 1021919 = 1021938
31 + 1021907 = 1021938
41 + 1021897 = 1021938
59 + 1021879 = 1021938
89 + 1021849 = 1021938
101 + 1021837 = 1021938
107 + 1021831 = 1021938
131 + 1021807 = 1021938

Showing the first eight; more decompositions exist.
