Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51264, here are decompositions:

7 + 51257 = 51264
23 + 51241 = 51264
47 + 51217 = 51264
61 + 51203 = 51264
67 + 51197 = 51264
71 + 51193 = 51264
107 + 51157 = 51264
113 + 51151 = 51264

Showing the first eight; more decompositions exist.
