Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023780, here are decompositions:

11 + 1023769 = 1023780
29 + 1023751 = 1023780
47 + 1023733 = 1023780
59 + 1023721 = 1023780
61 + 1023719 = 1023780
83 + 1023697 = 1023780
127 + 1023653 = 1023780
137 + 1023643 = 1023780

Showing the first eight; more decompositions exist.
