Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532004, here are decompositions:

37 + 31531967 = 31532004
73 + 31531931 = 31532004
83 + 31531921 = 31532004
191 + 31531813 = 31532004
277 + 31531727 = 31532004
337 + 31531667 = 31532004
521 + 31531483 = 31532004
547 + 31531457 = 31532004

Showing the first eight; more decompositions exist.
