Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20136, here are decompositions:

7 + 20129 = 20136
13 + 20123 = 20136
19 + 20117 = 20136
23 + 20113 = 20136
29 + 20107 = 20136
47 + 20089 = 20136
73 + 20063 = 20136
89 + 20047 = 20136

Showing the first eight; more decompositions exist.
