Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532006, here are decompositions:

3 + 31532003 = 31532006
97 + 31531909 = 31532006
193 + 31531813 = 31532006
367 + 31531639 = 31532006
379 + 31531627 = 31532006
523 + 31531483 = 31532006
607 + 31531399 = 31532006
733 + 31531273 = 31532006

Showing the first eight; more decompositions exist.
