Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555528, here are decompositions:

11 + 33555517 = 33555528
29 + 33555499 = 33555528
31 + 33555497 = 33555528
47 + 33555481 = 33555528
59 + 33555469 = 33555528
67 + 33555461 = 33555528
79 + 33555449 = 33555528
89 + 33555439 = 33555528

Showing the first eight; more decompositions exist.
