Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33539538, here are decompositions:

5 + 33539533 = 33539538
7 + 33539531 = 33539538
29 + 33539509 = 33539538
47 + 33539491 = 33539538
79 + 33539459 = 33539538
107 + 33539431 = 33539538
181 + 33539357 = 33539538
229 + 33539309 = 33539538

Showing the first eight; more decompositions exist.
