Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156342, here are decompositions:

13 + 156329 = 156342
23 + 156319 = 156342
73 + 156269 = 156342
83 + 156259 = 156342
89 + 156253 = 156342
101 + 156241 = 156342
113 + 156229 = 156342
191 + 156151 = 156342

Showing the first eight; more decompositions exist.
