Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582048, here are decompositions:

5 + 31582043 = 31582048
11 + 31582037 = 31582048
101 + 31581947 = 31582048
137 + 31581911 = 31582048
167 + 31581881 = 31582048
269 + 31581779 = 31582048
317 + 31581731 = 31582048
347 + 31581701 = 31582048

Showing the first eight; more decompositions exist.
