Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33539490, here are decompositions:

31 + 33539459 = 33539490
59 + 33539431 = 33539490
97 + 33539393 = 33539490
157 + 33539333 = 33539490
167 + 33539323 = 33539490
181 + 33539309 = 33539490
191 + 33539299 = 33539490
197 + 33539293 = 33539490

Showing the first eight; more decompositions exist.
