Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38740, here are decompositions:

3 + 38737 = 38740
11 + 38729 = 38740
17 + 38723 = 38740
29 + 38711 = 38740
41 + 38699 = 38740
47 + 38693 = 38740
71 + 38669 = 38740
89 + 38651 = 38740

Showing the first eight; more decompositions exist.
