Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593932, here are decompositions:

31 + 31593901 = 31593932
211 + 31593721 = 31593932
229 + 31593703 = 31593932
379 + 31593553 = 31593932
421 + 31593511 = 31593932
541 + 31593391 = 31593932
619 + 31593313 = 31593932
739 + 31593193 = 31593932

Showing the first eight; more decompositions exist.
