Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522032, here are decompositions:

11 + 31522021 = 31522032
13 + 31522019 = 31522032
19 + 31522013 = 31522032
41 + 31521991 = 31522032
53 + 31521979 = 31522032
79 + 31521953 = 31522032
149 + 31521883 = 31522032
181 + 31521851 = 31522032

Showing the first eight; more decompositions exist.
