Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51320, here are decompositions:

13 + 51307 = 51320
37 + 51283 = 51320
79 + 51241 = 51320
103 + 51217 = 51320
127 + 51193 = 51320
151 + 51169 = 51320
163 + 51157 = 51320
211 + 51109 = 51320

Showing the first eight; more decompositions exist.
