Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526198, here are decompositions:

7 + 31526191 = 31526198
241 + 31525957 = 31526198
271 + 31525927 = 31526198
307 + 31525891 = 31526198
349 + 31525849 = 31526198
421 + 31525777 = 31526198
499 + 31525699 = 31526198
541 + 31525657 = 31526198

Showing the first eight; more decompositions exist.
