Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521312, here are decompositions:

229 + 33521083 = 33521312
373 + 33520939 = 33521312
421 + 33520891 = 33521312
499 + 33520813 = 33521312
631 + 33520681 = 33521312
691 + 33520621 = 33521312
709 + 33520603 = 33521312
751 + 33520561 = 33521312

Showing the first eight; more decompositions exist.
