Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9880, here are decompositions:

23 + 9857 = 9880
29 + 9851 = 9880
41 + 9839 = 9880
47 + 9833 = 9880
89 + 9791 = 9880
113 + 9767 = 9880
131 + 9749 = 9880
137 + 9743 = 9880

Showing the first eight; more decompositions exist.
