Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39886, here are decompositions:

3 + 39883 = 39886
17 + 39869 = 39886
23 + 39863 = 39886
29 + 39857 = 39886
47 + 39839 = 39886
59 + 39827 = 39886
107 + 39779 = 39886
137 + 39749 = 39886

Showing the first eight; more decompositions exist.
