Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67740, here are decompositions:

7 + 67733 = 67740
17 + 67723 = 67740
31 + 67709 = 67740
41 + 67699 = 67740
61 + 67679 = 67740
89 + 67651 = 67740
109 + 67631 = 67740
139 + 67601 = 67740

Showing the first eight; more decompositions exist.
