Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475296, here are decompositions:

53 + 31475243 = 31475296
107 + 31475189 = 31475296
137 + 31475159 = 31475296
197 + 31475099 = 31475296
227 + 31475069 = 31475296
467 + 31474829 = 31475296
563 + 31474733 = 31475296
719 + 31474577 = 31475296

Showing the first eight; more decompositions exist.
