Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562304, here are decompositions:

5 + 31562299 = 31562304
13 + 31562291 = 31562304
23 + 31562281 = 31562304
31 + 31562273 = 31562304
41 + 31562263 = 31562304
43 + 31562261 = 31562304
47 + 31562257 = 31562304
61 + 31562243 = 31562304

Showing the first eight; more decompositions exist.
