Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15892, here are decompositions:

3 + 15889 = 15892
5 + 15887 = 15892
11 + 15881 = 15892
83 + 15809 = 15892
89 + 15803 = 15892
101 + 15791 = 15892
131 + 15761 = 15892
251 + 15641 = 15892

Showing the first eight; more decompositions exist.
