Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464448, here are decompositions:

5 + 31464443 = 31464448
47 + 31464401 = 31464448
89 + 31464359 = 31464448
107 + 31464341 = 31464448
167 + 31464281 = 31464448
179 + 31464269 = 31464448
311 + 31464137 = 31464448
401 + 31464047 = 31464448

Showing the first eight; more decompositions exist.
