Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005858, here are decompositions:

31 + 1005827 = 1005858
37 + 1005821 = 1005858
97 + 1005761 = 1005858
107 + 1005751 = 1005858
149 + 1005709 = 1005858
157 + 1005701 = 1005858
179 + 1005679 = 1005858
181 + 1005677 = 1005858

Showing the first eight; more decompositions exist.
