Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9956, here are decompositions:

7 + 9949 = 9956
73 + 9883 = 9956
97 + 9859 = 9956
127 + 9829 = 9956
139 + 9817 = 9956
223 + 9733 = 9956
277 + 9679 = 9956
307 + 9649 = 9956

Showing the first eight; more decompositions exist.
