Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71328, here are decompositions:

11 + 71317 = 71328
41 + 71287 = 71328
67 + 71261 = 71328
71 + 71257 = 71328
79 + 71249 = 71328
137 + 71191 = 71328
157 + 71171 = 71328
167 + 71161 = 71328

Showing the first eight; more decompositions exist.
