Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456522, here are decompositions:

5 + 31456517 = 31456522
191 + 31456331 = 31456522
263 + 31456259 = 31456522
281 + 31456241 = 31456522
359 + 31456163 = 31456522
401 + 31456121 = 31456522
443 + 31456079 = 31456522
509 + 31456013 = 31456522

Showing the first eight; more decompositions exist.
