Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9910, here are decompositions:

3 + 9907 = 9910
23 + 9887 = 9910
53 + 9857 = 9910
59 + 9851 = 9910
71 + 9839 = 9910
107 + 9803 = 9910
167 + 9743 = 9910
191 + 9719 = 9910

Showing the first eight; more decompositions exist.
