Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33518550, here are decompositions:

11 + 33518539 = 33518550
53 + 33518497 = 33518550
59 + 33518491 = 33518550
97 + 33518453 = 33518550
101 + 33518449 = 33518550
113 + 33518437 = 33518550
157 + 33518393 = 33518550
199 + 33518351 = 33518550

Showing the first eight; more decompositions exist.
