Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582022, here are decompositions:

19 + 31582003 = 31582022
61 + 31581961 = 31582022
139 + 31581883 = 31582022
163 + 31581859 = 31582022
229 + 31581793 = 31582022
313 + 31581709 = 31582022
349 + 31581673 = 31582022
379 + 31581643 = 31582022

Showing the first eight; more decompositions exist.
