Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39928, here are decompositions:

41 + 39887 = 39928
59 + 39869 = 39928
71 + 39857 = 39928
89 + 39839 = 39928
101 + 39827 = 39928
107 + 39821 = 39928
137 + 39791 = 39928
149 + 39779 = 39928

Showing the first eight; more decompositions exist.
