Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31834, here are decompositions:

17 + 31817 = 31834
41 + 31793 = 31834
83 + 31751 = 31834
107 + 31727 = 31834
113 + 31721 = 31834
167 + 31667 = 31834
191 + 31643 = 31834
227 + 31607 = 31834

Showing the first eight; more decompositions exist.
