Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13782, here are decompositions:

19 + 13763 = 13782
23 + 13759 = 13782
31 + 13751 = 13782
53 + 13729 = 13782
59 + 13723 = 13782
61 + 13721 = 13782
71 + 13711 = 13782
73 + 13709 = 13782

Showing the first eight; more decompositions exist.
