Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51378, here are decompositions:

17 + 51361 = 51378
29 + 51349 = 51378
31 + 51347 = 51378
37 + 51341 = 51378
71 + 51307 = 51378
137 + 51241 = 51378
139 + 51239 = 51378
149 + 51229 = 51378

Showing the first eight; more decompositions exist.
