Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522116, here are decompositions:

13 + 31522103 = 31522116
97 + 31522019 = 31522116
103 + 31522013 = 31522116
137 + 31521979 = 31522116
139 + 31521977 = 31522116
163 + 31521953 = 31522116
229 + 31521887 = 31522116
233 + 31521883 = 31522116

Showing the first eight; more decompositions exist.
