Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562328, here are decompositions:

29 + 31562299 = 31562328
37 + 31562291 = 31562328
47 + 31562281 = 31562328
67 + 31562261 = 31562328
71 + 31562257 = 31562328
97 + 31562231 = 31562328
191 + 31562137 = 31562328
211 + 31562117 = 31562328

Showing the first eight; more decompositions exist.
