Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156258, here are decompositions:

5 + 156253 = 156258
17 + 156241 = 156258
29 + 156229 = 156258
31 + 156227 = 156258
41 + 156217 = 156258
101 + 156157 = 156258
107 + 156151 = 156258
127 + 156131 = 156258

Showing the first eight; more decompositions exist.
