Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005726, here are decompositions:

17 + 1005709 = 1005726
47 + 1005679 = 1005726
79 + 1005647 = 1005726
83 + 1005643 = 1005726
89 + 1005637 = 1005726
107 + 1005619 = 1005726
109 + 1005617 = 1005726
173 + 1005553 = 1005726

Showing the first eight; more decompositions exist.
