Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91972, here are decompositions:

3 + 91969 = 91972
5 + 91967 = 91972
11 + 91961 = 91972
29 + 91943 = 91972
131 + 91841 = 91972
149 + 91823 = 91972
191 + 91781 = 91972
239 + 91733 = 91972

Showing the first eight; more decompositions exist.
