Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542208, here are decompositions:

11 + 31542197 = 31542208
59 + 31542149 = 31542208
197 + 31542011 = 31542208
227 + 31541981 = 31542208
317 + 31541891 = 31542208
557 + 31541651 = 31542208
617 + 31541591 = 31542208
701 + 31541507 = 31542208

Showing the first eight; more decompositions exist.
