Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582532, here are decompositions:

19 + 31582513 = 31582532
43 + 31582489 = 31582532
61 + 31582471 = 31582532
199 + 31582333 = 31582532
211 + 31582321 = 31582532
283 + 31582249 = 31582532
349 + 31582183 = 31582532
439 + 31582093 = 31582532

Showing the first eight; more decompositions exist.
