Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554024, here are decompositions:

11 + 31554013 = 31554024
13 + 31554011 = 31554024
31 + 31553993 = 31554024
37 + 31553987 = 31554024
41 + 31553983 = 31554024
157 + 31553867 = 31554024
191 + 31553833 = 31554024
223 + 31553801 = 31554024

Showing the first eight; more decompositions exist.
