Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005966, here are decompositions:

7 + 1005959 = 1005966
29 + 1005937 = 1005966
53 + 1005913 = 1005966
83 + 1005883 = 1005966
139 + 1005827 = 1005966
257 + 1005709 = 1005966
347 + 1005619 = 1005966
349 + 1005617 = 1005966

Showing the first eight; more decompositions exist.
