Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520446, here are decompositions:

29 + 31520417 = 31520446
47 + 31520399 = 31520446
53 + 31520393 = 31520446
59 + 31520387 = 31520446
107 + 31520339 = 31520446
137 + 31520309 = 31520446
509 + 31519937 = 31520446
557 + 31519889 = 31520446

Showing the first eight; more decompositions exist.
