Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513860, here are decompositions:

19 + 33513841 = 33513860
199 + 33513661 = 33513860
229 + 33513631 = 33513860
313 + 33513547 = 33513860
421 + 33513439 = 33513860
439 + 33513421 = 33513860
487 + 33513373 = 33513860
613 + 33513247 = 33513860

Showing the first eight; more decompositions exist.
