Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20124, here are decompositions:

7 + 20117 = 20124
11 + 20113 = 20124
17 + 20107 = 20124
23 + 20101 = 20124
53 + 20071 = 20124
61 + 20063 = 20124
73 + 20051 = 20124
101 + 20023 = 20124

Showing the first eight; more decompositions exist.
