Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39660, here are decompositions:

29 + 39631 = 39660
37 + 39623 = 39660
41 + 39619 = 39660
53 + 39607 = 39660
79 + 39581 = 39660
97 + 39563 = 39660
109 + 39551 = 39660
139 + 39521 = 39660

Showing the first eight; more decompositions exist.
