Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13830, here are decompositions:

23 + 13807 = 13830
31 + 13799 = 13830
41 + 13789 = 13830
67 + 13763 = 13830
71 + 13759 = 13830
73 + 13757 = 13830
79 + 13751 = 13830
101 + 13729 = 13830

Showing the first eight; more decompositions exist.
