Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9950, here are decompositions:

19 + 9931 = 9950
43 + 9907 = 9950
67 + 9883 = 9950
79 + 9871 = 9950
139 + 9811 = 9950
163 + 9787 = 9950
181 + 9769 = 9950
211 + 9739 = 9950

Showing the first eight; more decompositions exist.
