Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39040, here are decompositions:

17 + 39023 = 39040
47 + 38993 = 39040
107 + 38933 = 39040
137 + 38903 = 39040
149 + 38891 = 39040
167 + 38873 = 39040
173 + 38867 = 39040
179 + 38861 = 39040

Showing the first eight; more decompositions exist.
