Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554304, here are decompositions:

17 + 31554287 = 31554304
227 + 31554077 = 31554304
293 + 31554011 = 31554304
311 + 31553993 = 31554304
317 + 31553987 = 31554304
401 + 31553903 = 31554304
503 + 31553801 = 31554304
521 + 31553783 = 31554304

Showing the first eight; more decompositions exist.
