Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527856, here are decompositions:

29 + 31527827 = 31527856
167 + 31527689 = 31527856
179 + 31527677 = 31527856
197 + 31527659 = 31527856
359 + 31527497 = 31527856
443 + 31527413 = 31527856
449 + 31527407 = 31527856
467 + 31527389 = 31527856

Showing the first eight; more decompositions exist.
