Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582396, here are decompositions:

59 + 31582337 = 31582396
179 + 31582217 = 31582396
233 + 31582163 = 31582396
347 + 31582049 = 31582396
353 + 31582043 = 31582396
359 + 31582037 = 31582396
449 + 31581947 = 31582396
617 + 31581779 = 31582396

Showing the first eight; more decompositions exist.
