Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513680, here are decompositions:

7 + 33513673 = 33513680
19 + 33513661 = 33513680
139 + 33513541 = 33513680
181 + 33513499 = 33513680
223 + 33513457 = 33513680
241 + 33513439 = 33513680
307 + 33513373 = 33513680
313 + 33513367 = 33513680

Showing the first eight; more decompositions exist.
