Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582336, here are decompositions:

3 + 31582333 = 31582336
17 + 31582319 = 31582336
173 + 31582163 = 31582336
239 + 31582097 = 31582336
293 + 31582043 = 31582336
353 + 31581983 = 31582336
389 + 31581947 = 31582336
557 + 31581779 = 31582336

Showing the first eight; more decompositions exist.
