Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005888, here are decompositions:

5 + 1005883 = 1005888
61 + 1005827 = 1005888
67 + 1005821 = 1005888
127 + 1005761 = 1005888
137 + 1005751 = 1005888
179 + 1005709 = 1005888
211 + 1005677 = 1005888
227 + 1005661 = 1005888

Showing the first eight; more decompositions exist.
