Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33539472, here are decompositions:

13 + 33539459 = 33539472
41 + 33539431 = 33539472
59 + 33539413 = 33539472
79 + 33539393 = 33539472
139 + 33539333 = 33539472
149 + 33539323 = 33539472
163 + 33539309 = 33539472
173 + 33539299 = 33539472

Showing the first eight; more decompositions exist.
