Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513518, here are decompositions:

19 + 33513499 = 33513518
61 + 33513457 = 33513518
79 + 33513439 = 33513518
97 + 33513421 = 33513518
151 + 33513367 = 33513518
271 + 33513247 = 33513518
331 + 33513187 = 33513518
421 + 33513097 = 33513518

Showing the first eight; more decompositions exist.
