Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51306, here are decompositions:

19 + 51287 = 51306
23 + 51283 = 51306
43 + 51263 = 51306
67 + 51239 = 51306
89 + 51217 = 51306
103 + 51203 = 51306
107 + 51199 = 51306
109 + 51197 = 51306

Showing the first eight; more decompositions exist.
