Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522056, here are decompositions:

37 + 31522019 = 31522056
43 + 31522013 = 31522056
79 + 31521977 = 31522056
103 + 31521953 = 31522056
173 + 31521883 = 31522056
193 + 31521863 = 31522056
227 + 31521829 = 31522056
263 + 31521793 = 31522056

Showing the first eight; more decompositions exist.
