Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521072, here are decompositions:

181 + 33520891 = 33521072
229 + 33520843 = 33521072
271 + 33520801 = 33521072
313 + 33520759 = 33521072
601 + 33520471 = 33521072
643 + 33520429 = 33521072
709 + 33520363 = 33521072
751 + 33520321 = 33521072

Showing the first eight; more decompositions exist.
