Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51258, here are decompositions:

17 + 51241 = 51258
19 + 51239 = 51258
29 + 51229 = 51258
41 + 51217 = 51258
59 + 51199 = 51258
61 + 51197 = 51258
89 + 51169 = 51258
101 + 51157 = 51258

Showing the first eight; more decompositions exist.
