Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532008, here are decompositions:

5 + 31532003 = 31532008
41 + 31531967 = 31532008
191 + 31531817 = 31532008
257 + 31531751 = 31532008
281 + 31531727 = 31532008
359 + 31531649 = 31532008
587 + 31531421 = 31532008
929 + 31531079 = 31532008

Showing the first eight; more decompositions exist.
