Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527556, here are decompositions:

23 + 31527533 = 31527556
59 + 31527497 = 31527556
149 + 31527407 = 31527556
167 + 31527389 = 31527556
233 + 31527323 = 31527556
239 + 31527317 = 31527556
383 + 31527173 = 31527556
449 + 31527107 = 31527556

Showing the first eight; more decompositions exist.
