Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472008, here are decompositions:

5 + 31472003 = 31472008
17 + 31471991 = 31472008
41 + 31471967 = 31472008
101 + 31471907 = 31472008
107 + 31471901 = 31472008
311 + 31471697 = 31472008
431 + 31471577 = 31472008
569 + 31471439 = 31472008

Showing the first eight; more decompositions exist.
