Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562916, here are decompositions:

5 + 31562911 = 31562916
67 + 31562849 = 31562916
89 + 31562827 = 31562916
137 + 31562779 = 31562916
139 + 31562777 = 31562916
149 + 31562767 = 31562916
179 + 31562737 = 31562916
233 + 31562683 = 31562916

Showing the first eight; more decompositions exist.
