Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527376, here are decompositions:

53 + 31527323 = 31527376
59 + 31527317 = 31527376
227 + 31527149 = 31527376
233 + 31527143 = 31527376
269 + 31527107 = 31527376
359 + 31527017 = 31527376
449 + 31526927 = 31527376
557 + 31526819 = 31527376

Showing the first eight; more decompositions exist.
