Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582352, here are decompositions:

19 + 31582333 = 31582352
31 + 31582321 = 31582352
103 + 31582249 = 31582352
181 + 31582171 = 31582352
331 + 31582021 = 31582352
349 + 31582003 = 31582352
379 + 31581973 = 31582352
463 + 31581889 = 31582352

Showing the first eight; more decompositions exist.
