Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39874, here are decompositions:

5 + 39869 = 39874
11 + 39863 = 39874
17 + 39857 = 39874
47 + 39827 = 39874
53 + 39821 = 39874
83 + 39791 = 39874
113 + 39761 = 39874
251 + 39623 = 39874

Showing the first eight; more decompositions exist.
