Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20122, here are decompositions:

5 + 20117 = 20122
59 + 20063 = 20122
71 + 20051 = 20122
101 + 20021 = 20122
131 + 19991 = 20122
149 + 19973 = 20122
173 + 19949 = 20122
233 + 19889 = 20122

Showing the first eight; more decompositions exist.
