Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39910, here are decompositions:

23 + 39887 = 39910
41 + 39869 = 39910
47 + 39863 = 39910
53 + 39857 = 39910
71 + 39839 = 39910
83 + 39827 = 39910
89 + 39821 = 39910
131 + 39779 = 39910

Showing the first eight; more decompositions exist.
