Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521540, here are decompositions:

79 + 33521461 = 33521540
103 + 33521437 = 33521540
109 + 33521431 = 33521540
139 + 33521401 = 33521540
457 + 33521083 = 33521540
601 + 33520939 = 33521540
727 + 33520813 = 33521540
739 + 33520801 = 33521540

Showing the first eight; more decompositions exist.
