Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39728, here are decompositions:

19 + 39709 = 39728
61 + 39667 = 39728
97 + 39631 = 39728
109 + 39619 = 39728
229 + 39499 = 39728
277 + 39451 = 39728
331 + 39397 = 39728
487 + 39241 = 39728

Showing the first eight; more decompositions exist.
