Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563274, here are decompositions:

5 + 31563269 = 31563274
53 + 31563221 = 31563274
137 + 31563137 = 31563274
233 + 31563041 = 31563274
293 + 31562981 = 31563274
563 + 31562711 = 31563274
647 + 31562627 = 31563274
653 + 31562621 = 31563274

Showing the first eight; more decompositions exist.
