Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521384, here are decompositions:

163 + 33521221 = 33521384
397 + 33520987 = 33521384
541 + 33520843 = 33521384
571 + 33520813 = 33521384
601 + 33520783 = 33521384
607 + 33520777 = 33521384
823 + 33520561 = 33521384
907 + 33520477 = 33521384

Showing the first eight; more decompositions exist.
