Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021926, here are decompositions:

7 + 1021919 = 1021926
19 + 1021907 = 1021926
29 + 1021897 = 1021926
47 + 1021879 = 1021926
89 + 1021837 = 1021926
127 + 1021799 = 1021926
149 + 1021777 = 1021926
167 + 1021759 = 1021926

Showing the first eight; more decompositions exist.
