Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532052, here are decompositions:

31 + 31532021 = 31532052
131 + 31531921 = 31532052
239 + 31531813 = 31532052
373 + 31531679 = 31532052
569 + 31531483 = 31532052
599 + 31531453 = 31532052
631 + 31531421 = 31532052
653 + 31531399 = 31532052

Showing the first eight; more decompositions exist.
