Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005874, here are decompositions:

41 + 1005833 = 1005874
47 + 1005827 = 1005874
53 + 1005821 = 1005874
113 + 1005761 = 1005874
173 + 1005701 = 1005874
197 + 1005677 = 1005874
227 + 1005647 = 1005874
257 + 1005617 = 1005874

Showing the first eight; more decompositions exist.
