Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156324, here are decompositions:

5 + 156319 = 156324
17 + 156307 = 156324
67 + 156257 = 156324
71 + 156253 = 156324
83 + 156241 = 156324
97 + 156227 = 156324
107 + 156217 = 156324
167 + 156157 = 156324

Showing the first eight; more decompositions exist.
