Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475176, here are decompositions:

17 + 31475159 = 31475176
107 + 31475069 = 31475176
167 + 31475009 = 31475176
179 + 31474997 = 31475176
347 + 31474829 = 31475176
443 + 31474733 = 31475176
503 + 31474673 = 31475176
599 + 31474577 = 31475176

Showing the first eight; more decompositions exist.
