Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15908, here are decompositions:

7 + 15901 = 15908
19 + 15889 = 15908
31 + 15877 = 15908
181 + 15727 = 15908
229 + 15679 = 15908
241 + 15667 = 15908
307 + 15601 = 15908
349 + 15559 = 15908

Showing the first eight; more decompositions exist.
