Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39880, here are decompositions:

3 + 39877 = 39880
11 + 39869 = 39880
17 + 39863 = 39880
23 + 39857 = 39880
41 + 39839 = 39880
53 + 39827 = 39880
59 + 39821 = 39880
89 + 39791 = 39880

Showing the first eight; more decompositions exist.
