Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521432, here are decompositions:

31 + 33521401 = 33521432
211 + 33521221 = 33521432
349 + 33521083 = 33521432
541 + 33520891 = 33521432
619 + 33520813 = 33521432
631 + 33520801 = 33521432
673 + 33520759 = 33521432
751 + 33520681 = 33521432

Showing the first eight; more decompositions exist.
