Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522022, here are decompositions:

3 + 31522019 = 31522022
31 + 31521991 = 31522022
43 + 31521979 = 31522022
139 + 31521883 = 31522022
193 + 31521829 = 31522022
229 + 31521793 = 31522022
283 + 31521739 = 31522022
349 + 31521673 = 31522022

Showing the first eight; more decompositions exist.
