Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562710, here are decompositions:

83 + 31562627 = 31562710
89 + 31562621 = 31562710
107 + 31562603 = 31562710
167 + 31562543 = 31562710
191 + 31562519 = 31562710
227 + 31562483 = 31562710
269 + 31562441 = 31562710
281 + 31562429 = 31562710

Showing the first eight; more decompositions exist.
