Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38864, here are decompositions:

3 + 38861 = 38864
13 + 38851 = 38864
31 + 38833 = 38864
43 + 38821 = 38864
61 + 38803 = 38864
73 + 38791 = 38864
97 + 38767 = 38864
127 + 38737 = 38864

Showing the first eight; more decompositions exist.
