Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471198, here are decompositions:

89 + 31471109 = 31471198
107 + 31471091 = 31471198
167 + 31471031 = 31471198
191 + 31471007 = 31471198
197 + 31471001 = 31471198
257 + 31470941 = 31471198
281 + 31470917 = 31471198
557 + 31470641 = 31471198

Showing the first eight; more decompositions exist.
