Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39904, here are decompositions:

3 + 39901 = 39904
17 + 39887 = 39904
41 + 39863 = 39904
47 + 39857 = 39904
83 + 39821 = 39904
113 + 39791 = 39904
233 + 39671 = 39904
281 + 39623 = 39904

Showing the first eight; more decompositions exist.
