Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9980, here are decompositions:

7 + 9973 = 9980
13 + 9967 = 9980
31 + 9949 = 9980
73 + 9907 = 9980
79 + 9901 = 9980
97 + 9883 = 9980
109 + 9871 = 9980
151 + 9829 = 9980

Showing the first eight; more decompositions exist.
