Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33515550, here are decompositions:

11 + 33515539 = 33515550
31 + 33515519 = 33515550
41 + 33515509 = 33515550
113 + 33515437 = 33515550
181 + 33515369 = 33515550
191 + 33515359 = 33515550
193 + 33515357 = 33515550
227 + 33515323 = 33515550

Showing the first eight; more decompositions exist.
