Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562456, here are decompositions:

7 + 31562449 = 31562456
67 + 31562389 = 31562456
109 + 31562347 = 31562456
127 + 31562329 = 31562456
157 + 31562299 = 31562456
193 + 31562263 = 31562456
199 + 31562257 = 31562456
337 + 31562119 = 31562456

Showing the first eight; more decompositions exist.
