Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023828, here are decompositions:

7 + 1023821 = 1023828
59 + 1023769 = 1023828
97 + 1023731 = 1023828
107 + 1023721 = 1023828
109 + 1023719 = 1023828
131 + 1023697 = 1023828
227 + 1023601 = 1023828
251 + 1023577 = 1023828

Showing the first eight; more decompositions exist.
