Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9904, here are decompositions:

3 + 9901 = 9904
17 + 9887 = 9904
47 + 9857 = 9904
53 + 9851 = 9904
71 + 9833 = 9904
101 + 9803 = 9904
113 + 9791 = 9904
137 + 9767 = 9904

Showing the first eight; more decompositions exist.
