Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39760, here are decompositions:

11 + 39749 = 39760
41 + 39719 = 39760
89 + 39671 = 39760
101 + 39659 = 39760
137 + 39623 = 39760
179 + 39581 = 39760
191 + 39569 = 39760
197 + 39563 = 39760

Showing the first eight; more decompositions exist.
