Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005850, here are decompositions:

17 + 1005833 = 1005850
23 + 1005827 = 1005850
29 + 1005821 = 1005850
89 + 1005761 = 1005850
149 + 1005701 = 1005850
173 + 1005677 = 1005850
233 + 1005617 = 1005850
257 + 1005593 = 1005850

Showing the first eight; more decompositions exist.
