Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522026, here are decompositions:

5 + 31522021 = 31522026
7 + 31522019 = 31522026
13 + 31522013 = 31522026
47 + 31521979 = 31522026
73 + 31521953 = 31522026
139 + 31521887 = 31522026
163 + 31521863 = 31522026
197 + 31521829 = 31522026

Showing the first eight; more decompositions exist.
