Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554256, here are decompositions:

113 + 31554143 = 31554256
179 + 31554077 = 31554256
263 + 31553993 = 31554256
269 + 31553987 = 31554256
353 + 31553903 = 31554256
389 + 31553867 = 31554256
449 + 31553807 = 31554256
479 + 31553777 = 31554256

Showing the first eight; more decompositions exist.
