Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021986, here are decompositions:

13 + 1021973 = 1021986
23 + 1021963 = 1021986
67 + 1021919 = 1021986
79 + 1021907 = 1021986
89 + 1021897 = 1021986
107 + 1021879 = 1021986
137 + 1021849 = 1021986
149 + 1021837 = 1021986

Showing the first eight; more decompositions exist.
