Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20118, here are decompositions:

5 + 20113 = 20118
11 + 20107 = 20118
17 + 20101 = 20118
29 + 20089 = 20118
47 + 20071 = 20118
67 + 20051 = 20118
71 + 20047 = 20118
89 + 20029 = 20118

Showing the first eight; more decompositions exist.
