Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20148, here are decompositions:

5 + 20143 = 20148
19 + 20129 = 20148
31 + 20117 = 20148
41 + 20107 = 20148
47 + 20101 = 20148
59 + 20089 = 20148
97 + 20051 = 20148
101 + 20047 = 20148

Showing the first eight; more decompositions exist.
