Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593812, here are decompositions:

109 + 31593703 = 31593812
181 + 31593631 = 31593812
199 + 31593613 = 31593812
223 + 31593589 = 31593812
241 + 31593571 = 31593812
421 + 31593391 = 31593812
499 + 31593313 = 31593812
619 + 31593193 = 31593812

Showing the first eight; more decompositions exist.
