Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68740, here are decompositions:

3 + 68737 = 68740
11 + 68729 = 68740
29 + 68711 = 68740
41 + 68699 = 68740
53 + 68687 = 68740
71 + 68669 = 68740
101 + 68639 = 68740
107 + 68633 = 68740

Showing the first eight; more decompositions exist.
