Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51388, here are decompositions:

5 + 51383 = 51388
41 + 51347 = 51388
47 + 51341 = 51388
59 + 51329 = 51388
101 + 51287 = 51388
131 + 51257 = 51388
149 + 51239 = 51388
191 + 51197 = 51388

Showing the first eight; more decompositions exist.
