Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521516, here are decompositions:

79 + 33521437 = 33521516
337 + 33521179 = 33521516
433 + 33521083 = 33521516
577 + 33520939 = 33521516
673 + 33520843 = 33521516
733 + 33520783 = 33521516
739 + 33520777 = 33521516
757 + 33520759 = 33521516

Showing the first eight; more decompositions exist.
