Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71740, here are decompositions:

29 + 71711 = 71740
41 + 71699 = 71740
47 + 71693 = 71740
107 + 71633 = 71740
191 + 71549 = 71740
257 + 71483 = 71740
269 + 71471 = 71740
311 + 71429 = 71740

Showing the first eight; more decompositions exist.
