Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71380, here are decompositions:

17 + 71363 = 71380
41 + 71339 = 71380
47 + 71333 = 71380
53 + 71327 = 71380
131 + 71249 = 71380
227 + 71153 = 71380
233 + 71147 = 71380
251 + 71129 = 71380

Showing the first eight; more decompositions exist.
