Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20112, here are decompositions:

5 + 20107 = 20112
11 + 20101 = 20112
23 + 20089 = 20112
41 + 20071 = 20112
61 + 20051 = 20112
83 + 20029 = 20112
89 + 20023 = 20112
101 + 20011 = 20112

Showing the first eight; more decompositions exist.
