Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475006, here are decompositions:

7 + 31474999 = 31475006
37 + 31474969 = 31475006
139 + 31474867 = 31475006
223 + 31474783 = 31475006
229 + 31474777 = 31475006
313 + 31474693 = 31475006
337 + 31474669 = 31475006
457 + 31474549 = 31475006

Showing the first eight; more decompositions exist.
