Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562934, here are decompositions:

17 + 31562917 = 31562934
23 + 31562911 = 31562934
107 + 31562827 = 31562934
157 + 31562777 = 31562934
167 + 31562767 = 31562934
197 + 31562737 = 31562934
223 + 31562711 = 31562934
251 + 31562683 = 31562934

Showing the first eight; more decompositions exist.
