Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15886, here are decompositions:

5 + 15881 = 15886
83 + 15803 = 15886
89 + 15797 = 15886
113 + 15773 = 15886
137 + 15749 = 15886
149 + 15737 = 15886
239 + 15647 = 15886
257 + 15629 = 15886

Showing the first eight; more decompositions exist.
