Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020780, here are decompositions:

23 + 1020757 = 1020780
29 + 1020751 = 1020780
37 + 1020743 = 1020780
71 + 1020709 = 1020780
73 + 1020707 = 1020780
97 + 1020683 = 1020780
113 + 1020667 = 1020780
149 + 1020631 = 1020780

Showing the first eight; more decompositions exist.
