Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522110, here are decompositions:

7 + 31522103 = 31522110
19 + 31522091 = 31522110
89 + 31522021 = 31522110
97 + 31522013 = 31522110
131 + 31521979 = 31522110
157 + 31521953 = 31522110
223 + 31521887 = 31522110
227 + 31521883 = 31522110

Showing the first eight; more decompositions exist.
