Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005828, here are decompositions:

7 + 1005821 = 1005828
67 + 1005761 = 1005828
127 + 1005701 = 1005828
149 + 1005679 = 1005828
151 + 1005677 = 1005828
167 + 1005661 = 1005828
181 + 1005647 = 1005828
191 + 1005637 = 1005828

Showing the first eight; more decompositions exist.
