Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71340, here are decompositions:

7 + 71333 = 71340
11 + 71329 = 71340
13 + 71327 = 71340
23 + 71317 = 71340
47 + 71293 = 71340
53 + 71287 = 71340
79 + 71261 = 71340
83 + 71257 = 71340

Showing the first eight; more decompositions exist.
