Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001838, here are decompositions:

7 + 1001831 = 1001838
17 + 1001821 = 1001838
29 + 1001809 = 1001838
31 + 1001807 = 1001838
37 + 1001801 = 1001838
41 + 1001797 = 1001838
151 + 1001687 = 1001838
179 + 1001659 = 1001838

Showing the first eight; more decompositions exist.
