Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562484, here are decompositions:

17 + 31562467 = 31562484
43 + 31562441 = 31562484
53 + 31562431 = 31562484
61 + 31562423 = 31562484
127 + 31562357 = 31562484
137 + 31562347 = 31562484
193 + 31562291 = 31562484
211 + 31562273 = 31562484

Showing the first eight; more decompositions exist.
