Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562976, here are decompositions:

17 + 31562959 = 31562976
59 + 31562917 = 31562976
127 + 31562849 = 31562976
149 + 31562827 = 31562976
197 + 31562779 = 31562976
199 + 31562777 = 31562976
239 + 31562737 = 31562976
293 + 31562683 = 31562976

Showing the first eight; more decompositions exist.
