Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527892, here are decompositions:

5 + 31527887 = 31527892
191 + 31527701 = 31527892
233 + 31527659 = 31527892
359 + 31527533 = 31527892
401 + 31527491 = 31527892
479 + 31527413 = 31527892
503 + 31527389 = 31527892
569 + 31527323 = 31527892

Showing the first eight; more decompositions exist.
