Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582058, here are decompositions:

31 + 31582027 = 31582058
37 + 31582021 = 31582058
61 + 31581997 = 31582058
97 + 31581961 = 31582058
181 + 31581877 = 31582058
199 + 31581859 = 31582058
241 + 31581817 = 31582058
271 + 31581787 = 31582058

Showing the first eight; more decompositions exist.
