Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555680, here are decompositions:

13 + 33555667 = 33555680
19 + 33555661 = 33555680
97 + 33555583 = 33555680
127 + 33555553 = 33555680
163 + 33555517 = 33555680
181 + 33555499 = 33555680
199 + 33555481 = 33555680
211 + 33555469 = 33555680

Showing the first eight; more decompositions exist.
