Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1046720, here are decompositions:

19 + 1046701 = 1046720
43 + 1046677 = 1046720
61 + 1046659 = 1046720
79 + 1046641 = 1046720
163 + 1046557 = 1046720
193 + 1046527 = 1046720
223 + 1046497 = 1046720
271 + 1046449 = 1046720

Showing the first eight; more decompositions exist.
