Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20154, here are decompositions:

5 + 20149 = 20154
7 + 20147 = 20154
11 + 20143 = 20154
31 + 20123 = 20154
37 + 20117 = 20154
41 + 20113 = 20154
47 + 20107 = 20154
53 + 20101 = 20154

Showing the first eight; more decompositions exist.
