Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39818, here are decompositions:

19 + 39799 = 39818
109 + 39709 = 39818
139 + 39679 = 39818
151 + 39667 = 39818
199 + 39619 = 39818
211 + 39607 = 39818
277 + 39541 = 39818
307 + 39511 = 39818

Showing the first eight; more decompositions exist.
