Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538122, here are decompositions:

5 + 538117 = 538122
29 + 538093 = 538122
43 + 538079 = 538122
71 + 538051 = 538122
73 + 538049 = 538122
103 + 538019 = 538122
131 + 537991 = 538122
181 + 537941 = 538122

Showing the first eight; more decompositions exist.
