Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15938, here are decompositions:

19 + 15919 = 15938
31 + 15907 = 15938
37 + 15901 = 15938
61 + 15877 = 15938
79 + 15859 = 15938
151 + 15787 = 15938
199 + 15739 = 15938
211 + 15727 = 15938

Showing the first eight; more decompositions exist.
