Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15922, here are decompositions:

3 + 15919 = 15922
41 + 15881 = 15922
113 + 15809 = 15922
131 + 15791 = 15922
149 + 15773 = 15922
173 + 15749 = 15922
191 + 15731 = 15922
239 + 15683 = 15922

Showing the first eight; more decompositions exist.
