Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023858, here are decompositions:

7 + 1023851 = 1023858
19 + 1023839 = 1023858
37 + 1023821 = 1023858
89 + 1023769 = 1023858
107 + 1023751 = 1023858
127 + 1023731 = 1023858
137 + 1023721 = 1023858
139 + 1023719 = 1023858

Showing the first eight; more decompositions exist.
