Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527874, here are decompositions:

47 + 31527827 = 31527874
173 + 31527701 = 31527874
197 + 31527677 = 31527874
353 + 31527521 = 31527874
383 + 31527491 = 31527874
461 + 31527413 = 31527874
467 + 31527407 = 31527874
557 + 31527317 = 31527874

Showing the first eight; more decompositions exist.
