Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553708, here are decompositions:

37 + 31553671 = 31553708
181 + 31553527 = 31553708
349 + 31553359 = 31553708
547 + 31553161 = 31553708
619 + 31553089 = 31553708
631 + 31553077 = 31553708
691 + 31553017 = 31553708
709 + 31552999 = 31553708

Showing the first eight; more decompositions exist.
