Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38920, here are decompositions:

3 + 38917 = 38920
17 + 38903 = 38920
29 + 38891 = 38920
47 + 38873 = 38920
53 + 38867 = 38920
59 + 38861 = 38920
137 + 38783 = 38920
173 + 38747 = 38920

Showing the first eight; more decompositions exist.
