Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39128, here are decompositions:

31 + 39097 = 39128
109 + 39019 = 39128
151 + 38977 = 39128
157 + 38971 = 39128
211 + 38917 = 39128
277 + 38851 = 39128
307 + 38821 = 39128
337 + 38791 = 39128

Showing the first eight; more decompositions exist.
