Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38872, here are decompositions:

5 + 38867 = 38872
11 + 38861 = 38872
89 + 38783 = 38872
149 + 38723 = 38872
173 + 38699 = 38872
179 + 38693 = 38872
233 + 38639 = 38872
263 + 38609 = 38872

Showing the first eight; more decompositions exist.
