Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156288, here are decompositions:

19 + 156269 = 156288
29 + 156259 = 156288
31 + 156257 = 156288
47 + 156241 = 156288
59 + 156229 = 156288
61 + 156227 = 156288
71 + 156217 = 156288
131 + 156157 = 156288

Showing the first eight; more decompositions exist.
