Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464496, here are decompositions:

3 + 31464493 = 31464496
53 + 31464443 = 31464496
137 + 31464359 = 31464496
227 + 31464269 = 31464496
263 + 31464233 = 31464496
347 + 31464149 = 31464496
353 + 31464143 = 31464496
359 + 31464137 = 31464496

Showing the first eight; more decompositions exist.
