Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542198, here are decompositions:

131 + 31542067 = 31542198
167 + 31542031 = 31542198
197 + 31542001 = 31542198
227 + 31541971 = 31542198
307 + 31541891 = 31542198
461 + 31541737 = 31542198
491 + 31541707 = 31542198
521 + 31541677 = 31542198

Showing the first eight; more decompositions exist.
