Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005990, here are decompositions:

19 + 1005971 = 1005990
31 + 1005959 = 1005990
53 + 1005937 = 1005990
59 + 1005931 = 1005990
79 + 1005911 = 1005990
107 + 1005883 = 1005990
157 + 1005833 = 1005990
163 + 1005827 = 1005990

Showing the first eight; more decompositions exist.
