Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9994, here are decompositions:

53 + 9941 = 9994
71 + 9923 = 9994
107 + 9887 = 9994
137 + 9857 = 9994
191 + 9803 = 9994
227 + 9767 = 9994
251 + 9743 = 9994
317 + 9677 = 9994

Showing the first eight; more decompositions exist.
