Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38886, here are decompositions:

13 + 38873 = 38886
19 + 38867 = 38886
47 + 38839 = 38886
53 + 38833 = 38886
83 + 38803 = 38886
103 + 38783 = 38886
137 + 38749 = 38886
139 + 38747 = 38886

Showing the first eight; more decompositions exist.
