Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562364, here are decompositions:

7 + 31562357 = 31562364
17 + 31562347 = 31562364
73 + 31562291 = 31562364
83 + 31562281 = 31562364
101 + 31562263 = 31562364
103 + 31562261 = 31562364
107 + 31562257 = 31562364
151 + 31562213 = 31562364

Showing the first eight; more decompositions exist.
