Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582384, here are decompositions:

47 + 31582337 = 31582384
167 + 31582217 = 31582384
191 + 31582193 = 31582384
263 + 31582121 = 31582384
347 + 31582037 = 31582384
401 + 31581983 = 31582384
503 + 31581881 = 31582384
521 + 31581863 = 31582384

Showing the first eight; more decompositions exist.
