Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39938, here are decompositions:

37 + 39901 = 39938
61 + 39877 = 39938
97 + 39841 = 39938
109 + 39829 = 39938
139 + 39799 = 39938
211 + 39727 = 39938
229 + 39709 = 39938
271 + 39667 = 39938

Showing the first eight; more decompositions exist.
