Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521408, here are decompositions:

7 + 33521401 = 33521408
229 + 33521179 = 33521408
421 + 33520987 = 33521408
607 + 33520801 = 33521408
631 + 33520777 = 33521408
727 + 33520681 = 33521408
787 + 33520621 = 33521408
919 + 33520489 = 33521408

Showing the first eight; more decompositions exist.
