Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20130, here are decompositions:

7 + 20123 = 20130
13 + 20117 = 20130
17 + 20113 = 20130
23 + 20107 = 20130
29 + 20101 = 20130
41 + 20089 = 20130
59 + 20071 = 20130
67 + 20063 = 20130

Showing the first eight; more decompositions exist.
