Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582484, here are decompositions:

13 + 31582471 = 31582484
67 + 31582417 = 31582484
151 + 31582333 = 31582484
163 + 31582321 = 31582484
277 + 31582207 = 31582484
313 + 31582171 = 31582484
457 + 31582027 = 31582484
463 + 31582021 = 31582484

Showing the first eight; more decompositions exist.
