Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51368, here are decompositions:

7 + 51361 = 51368
19 + 51349 = 51368
61 + 51307 = 51368
127 + 51241 = 51368
139 + 51229 = 51368
151 + 51217 = 51368
199 + 51169 = 51368
211 + 51157 = 51368

Showing the first eight; more decompositions exist.
