Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39986, here are decompositions:

3 + 39983 = 39986
7 + 39979 = 39986
103 + 39883 = 39986
109 + 39877 = 39986
139 + 39847 = 39986
157 + 39829 = 39986
277 + 39709 = 39986
283 + 39703 = 39986

Showing the first eight; more decompositions exist.
