Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961020, here are decompositions:

17 + 961003 = 961020
29 + 960991 = 961020
31 + 960989 = 961020
37 + 960983 = 961020
43 + 960977 = 961020
59 + 960961 = 961020
79 + 960941 = 961020
83 + 960937 = 961020

Showing the first eight; more decompositions exist.
