Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1029780, here are decompositions:

13 + 1029767 = 1029780
23 + 1029757 = 1029780
29 + 1029751 = 1029780
83 + 1029697 = 1029780
127 + 1029653 = 1029780
137 + 1029643 = 1029780
163 + 1029617 = 1029780
179 + 1029601 = 1029780

Showing the first eight; more decompositions exist.
