Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612022, here are decompositions:

139 + 31611883 = 31612022
181 + 31611841 = 31612022
193 + 31611829 = 31612022
313 + 31611709 = 31612022
349 + 31611673 = 31612022
439 + 31611583 = 31612022
619 + 31611403 = 31612022
643 + 31611379 = 31612022

Showing the first eight; more decompositions exist.
