Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475926, here are decompositions:

17 + 31475909 = 31475926
113 + 31475813 = 31475926
149 + 31475777 = 31475926
257 + 31475669 = 31475926
347 + 31475579 = 31475926
467 + 31475459 = 31475926
683 + 31475243 = 31475926
827 + 31475099 = 31475926

Showing the first eight; more decompositions exist.
