Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582562, here are decompositions:

3 + 31582559 = 31582562
31 + 31582531 = 31582562
73 + 31582489 = 31582562
163 + 31582399 = 31582562
229 + 31582333 = 31582562
241 + 31582321 = 31582562
313 + 31582249 = 31582562
379 + 31582183 = 31582562

Showing the first eight; more decompositions exist.
