Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554424, here are decompositions:

23 + 31554401 = 31554424
137 + 31554287 = 31554424
263 + 31554161 = 31554424
281 + 31554143 = 31554424
347 + 31554077 = 31554424
431 + 31553993 = 31554424
521 + 31553903 = 31554424
557 + 31553867 = 31554424

Showing the first eight; more decompositions exist.
