Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527388, here are decompositions:

71 + 31527317 = 31527388
197 + 31527191 = 31527388
239 + 31527149 = 31527388
257 + 31527131 = 31527388
281 + 31527107 = 31527388
311 + 31527077 = 31527388
449 + 31526939 = 31527388
461 + 31526927 = 31527388

Showing the first eight; more decompositions exist.
