Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521150, here are decompositions:

67 + 33521083 = 33521150
163 + 33520987 = 33521150
211 + 33520939 = 33521150
307 + 33520843 = 33521150
337 + 33520813 = 33521150
349 + 33520801 = 33521150
367 + 33520783 = 33521150
373 + 33520777 = 33521150

Showing the first eight; more decompositions exist.
