Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9902, here are decompositions:

19 + 9883 = 9902
31 + 9871 = 9902
43 + 9859 = 9902
73 + 9829 = 9902
163 + 9739 = 9902
181 + 9721 = 9902
223 + 9679 = 9902
241 + 9661 = 9902

Showing the first eight; more decompositions exist.
