Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521438, here are decompositions:

7 + 33521431 = 33521438
37 + 33521401 = 33521438
499 + 33520939 = 33521438
547 + 33520891 = 33521438
661 + 33520777 = 33521438
751 + 33520687 = 33521438
757 + 33520681 = 33521438
877 + 33520561 = 33521438

Showing the first eight; more decompositions exist.
