Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562360, here are decompositions:

3 + 31562357 = 31562360
13 + 31562347 = 31562360
31 + 31562329 = 31562360
61 + 31562299 = 31562360
79 + 31562281 = 31562360
97 + 31562263 = 31562360
103 + 31562257 = 31562360
223 + 31562137 = 31562360

Showing the first eight; more decompositions exist.
