Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39740, here are decompositions:

7 + 39733 = 39740
13 + 39727 = 39740
31 + 39709 = 39740
37 + 39703 = 39740
61 + 39679 = 39740
73 + 39667 = 39740
109 + 39631 = 39740
199 + 39541 = 39740

Showing the first eight; more decompositions exist.
