Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51318, here are decompositions:

11 + 51307 = 51318
31 + 51287 = 51318
61 + 51257 = 51318
79 + 51239 = 51318
89 + 51229 = 51318
101 + 51217 = 51318
149 + 51169 = 51318
167 + 51151 = 51318

Showing the first eight; more decompositions exist.
