Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9972, here are decompositions:

5 + 9967 = 9972
23 + 9949 = 9972
31 + 9941 = 9972
41 + 9931 = 9972
43 + 9929 = 9972
71 + 9901 = 9972
89 + 9883 = 9972
101 + 9871 = 9972

Showing the first eight; more decompositions exist.
