Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001868, here are decompositions:

29 + 1001839 = 1001868
37 + 1001831 = 1001868
47 + 1001821 = 1001868
59 + 1001809 = 1001868
61 + 1001807 = 1001868
67 + 1001801 = 1001868
71 + 1001797 = 1001868
181 + 1001687 = 1001868

Showing the first eight; more decompositions exist.
