Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39620, here are decompositions:

13 + 39607 = 39620
79 + 39541 = 39620
109 + 39511 = 39620
181 + 39439 = 39620
211 + 39409 = 39620
223 + 39397 = 39620
277 + 39343 = 39620
307 + 39313 = 39620

Showing the first eight; more decompositions exist.
