Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156312, here are decompositions:

5 + 156307 = 156312
43 + 156269 = 156312
53 + 156259 = 156312
59 + 156253 = 156312
71 + 156241 = 156312
83 + 156229 = 156312
173 + 156139 = 156312
181 + 156131 = 156312

Showing the first eight; more decompositions exist.
