Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 996720, here are decompositions:

17 + 996703 = 996720
31 + 996689 = 996720
71 + 996649 = 996720
73 + 996647 = 996720
83 + 996637 = 996720
89 + 996631 = 996720
103 + 996617 = 996720
149 + 996571 = 996720

Showing the first eight; more decompositions exist.
