Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005838, here are decompositions:

5 + 1005833 = 1005838
11 + 1005827 = 1005838
17 + 1005821 = 1005838
137 + 1005701 = 1005838
191 + 1005647 = 1005838
257 + 1005581 = 1005838
311 + 1005527 = 1005838
401 + 1005437 = 1005838

Showing the first eight; more decompositions exist.
