Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554016, here are decompositions:

3 + 31554013 = 31554016
5 + 31554011 = 31554016
23 + 31553993 = 31554016
29 + 31553987 = 31554016
113 + 31553903 = 31554016
149 + 31553867 = 31554016
233 + 31553783 = 31554016
239 + 31553777 = 31554016

Showing the first eight; more decompositions exist.
