Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562716, here are decompositions:

5 + 31562711 = 31562716
89 + 31562627 = 31562716
113 + 31562603 = 31562716
149 + 31562567 = 31562716
173 + 31562543 = 31562716
197 + 31562519 = 31562716
233 + 31562483 = 31562716
293 + 31562423 = 31562716

Showing the first eight; more decompositions exist.
