Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33545818, here are decompositions:

29 + 33545789 = 33545818
71 + 33545747 = 33545818
167 + 33545651 = 33545818
227 + 33545591 = 33545818
239 + 33545579 = 33545818
359 + 33545459 = 33545818
389 + 33545429 = 33545818
491 + 33545327 = 33545818

Showing the first eight; more decompositions exist.
