Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16902, here are decompositions:

13 + 16889 = 16902
19 + 16883 = 16902
23 + 16879 = 16902
31 + 16871 = 16902
59 + 16843 = 16902
71 + 16831 = 16902
73 + 16829 = 16902
79 + 16823 = 16902

Showing the first eight; more decompositions exist.
