Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475012, here are decompositions:

3 + 31475009 = 31475012
13 + 31474999 = 31475012
31 + 31474981 = 31475012
43 + 31474969 = 31475012
139 + 31474873 = 31475012
211 + 31474801 = 31475012
229 + 31474783 = 31475012
463 + 31474549 = 31475012

Showing the first eight; more decompositions exist.
