Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71288, here are decompositions:

31 + 71257 = 71288
79 + 71209 = 71288
97 + 71191 = 71288
127 + 71161 = 71288
199 + 71089 = 71288
229 + 71059 = 71288
277 + 71011 = 71288
307 + 70981 = 71288

Showing the first eight; more decompositions exist.
