Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553456, here are decompositions:

3 + 31553453 = 31553456
73 + 31553383 = 31553456
97 + 31553359 = 31553456
223 + 31553233 = 31553456
367 + 31553089 = 31553456
379 + 31553077 = 31553456
439 + 31553017 = 31553456
457 + 31552999 = 31553456

Showing the first eight; more decompositions exist.
