Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13810, here are decompositions:

3 + 13807 = 13810
11 + 13799 = 13810
29 + 13781 = 13810
47 + 13763 = 13810
53 + 13757 = 13810
59 + 13751 = 13810
89 + 13721 = 13810
101 + 13709 = 13810

Showing the first eight; more decompositions exist.
