Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522122, here are decompositions:

19 + 31522103 = 31522122
31 + 31522091 = 31522122
61 + 31522061 = 31522122
101 + 31522021 = 31522122
103 + 31522019 = 31522122
109 + 31522013 = 31522122
131 + 31521991 = 31522122
239 + 31521883 = 31522122

Showing the first eight; more decompositions exist.
