Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532632, here are decompositions:

59 + 31532573 = 31532632
293 + 31532339 = 31532632
353 + 31532279 = 31532632
491 + 31532141 = 31532632
569 + 31532063 = 31532632
701 + 31531931 = 31532632
881 + 31531751 = 31532632
953 + 31531679 = 31532632

Showing the first eight; more decompositions exist.
