Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532002, here are decompositions:

71 + 31531931 = 31532002
251 + 31531751 = 31532002
353 + 31531649 = 31532002
479 + 31531523 = 31532002
599 + 31531403 = 31532002
701 + 31531301 = 31532002
839 + 31531163 = 31532002
863 + 31531139 = 31532002

Showing the first eight; more decompositions exist.
