Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15902, here are decompositions:

13 + 15889 = 15902
43 + 15859 = 15902
79 + 15823 = 15902
163 + 15739 = 15902
223 + 15679 = 15902
241 + 15661 = 15902
283 + 15619 = 15902
409 + 15493 = 15902

Showing the first eight; more decompositions exist.
