Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522074, here are decompositions:

13 + 31522061 = 31522074
53 + 31522021 = 31522074
61 + 31522013 = 31522074
83 + 31521991 = 31522074
97 + 31521977 = 31522074
191 + 31521883 = 31522074
211 + 31521863 = 31522074
223 + 31521851 = 31522074

Showing the first eight; more decompositions exist.
