Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514008, here are decompositions:

41 + 31513967 = 31514008
131 + 31513877 = 31514008
191 + 31513817 = 31514008
269 + 31513739 = 31514008
311 + 31513697 = 31514008
347 + 31513661 = 31514008
401 + 31513607 = 31514008
677 + 31513331 = 31514008

Showing the first eight; more decompositions exist.
