Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527724, here are decompositions:

23 + 31527701 = 31527724
47 + 31527677 = 31527724
191 + 31527533 = 31527724
227 + 31527497 = 31527724
233 + 31527491 = 31527724
311 + 31527413 = 31527724
317 + 31527407 = 31527724
401 + 31527323 = 31527724

Showing the first eight; more decompositions exist.
