Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17956, here are decompositions:

17 + 17939 = 17956
47 + 17909 = 17956
53 + 17903 = 17956
149 + 17807 = 17956
167 + 17789 = 17956
173 + 17783 = 17956
227 + 17729 = 17956
347 + 17609 = 17956

Showing the first eight; more decompositions exist.
