Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71396, here are decompositions:

7 + 71389 = 71396
37 + 71359 = 71396
43 + 71353 = 71396
67 + 71329 = 71396
79 + 71317 = 71396
103 + 71293 = 71396
109 + 71287 = 71396
139 + 71257 = 71396

Showing the first eight; more decompositions exist.
