Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464456, here are decompositions:

5 + 31464451 = 31464456
13 + 31464443 = 31464456
17 + 31464439 = 31464456
29 + 31464427 = 31464456
47 + 31464409 = 31464456
59 + 31464397 = 31464456
97 + 31464359 = 31464456
223 + 31464233 = 31464456

Showing the first eight; more decompositions exist.
