Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517258, here are decompositions:

17 + 517241 = 517258
29 + 517229 = 517258
41 + 517217 = 517258
47 + 517211 = 517258
89 + 517169 = 517258
107 + 517151 = 517258
167 + 517091 = 517258
179 + 517079 = 517258

Showing the first eight; more decompositions exist.
