Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31026, here are decompositions:

7 + 31019 = 31026
13 + 31013 = 31026
43 + 30983 = 31026
89 + 30937 = 31026
157 + 30869 = 31026
167 + 30859 = 31026
173 + 30853 = 31026
197 + 30829 = 31026

Showing the first eight; more decompositions exist.
