Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15932, here are decompositions:

13 + 15919 = 15932
19 + 15913 = 15932
31 + 15901 = 15932
43 + 15889 = 15932
73 + 15859 = 15932
109 + 15823 = 15932
193 + 15739 = 15932
199 + 15733 = 15932

Showing the first eight; more decompositions exist.
