Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582334, here are decompositions:

13 + 31582321 = 31582334
67 + 31582267 = 31582334
127 + 31582207 = 31582334
151 + 31582183 = 31582334
163 + 31582171 = 31582334
241 + 31582093 = 31582334
307 + 31582027 = 31582334
313 + 31582021 = 31582334

Showing the first eight; more decompositions exist.
