Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513818, here are decompositions:

7 + 33513811 = 33513818
157 + 33513661 = 33513818
271 + 33513547 = 33513818
277 + 33513541 = 33513818
379 + 33513439 = 33513818
397 + 33513421 = 33513818
571 + 33513247 = 33513818
631 + 33513187 = 33513818

Showing the first eight; more decompositions exist.
