Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71320, here are decompositions:

3 + 71317 = 71320
59 + 71261 = 71320
71 + 71249 = 71320
83 + 71237 = 71320
149 + 71171 = 71320
167 + 71153 = 71320
173 + 71147 = 71320
191 + 71129 = 71320

Showing the first eight; more decompositions exist.
