Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474970, here are decompositions:

97 + 31474873 = 31474970
103 + 31474867 = 31474970
193 + 31474777 = 31474970
223 + 31474747 = 31474970
277 + 31474693 = 31474970
283 + 31474687 = 31474970
421 + 31474549 = 31474970
547 + 31474423 = 31474970

Showing the first eight; more decompositions exist.
