Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005720, here are decompositions:

11 + 1005709 = 1005720
19 + 1005701 = 1005720
41 + 1005679 = 1005720
43 + 1005677 = 1005720
59 + 1005661 = 1005720
73 + 1005647 = 1005720
83 + 1005637 = 1005720
101 + 1005619 = 1005720

Showing the first eight; more decompositions exist.
