Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582016, here are decompositions:

13 + 31582003 = 31582016
19 + 31581997 = 31582016
43 + 31581973 = 31582016
127 + 31581889 = 31582016
139 + 31581877 = 31582016
157 + 31581859 = 31582016
199 + 31581817 = 31582016
223 + 31581793 = 31582016

Showing the first eight; more decompositions exist.
