Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33517840, here are decompositions:

29 + 33517811 = 33517840
47 + 33517793 = 33517840
227 + 33517613 = 33517840
281 + 33517559 = 33517840
359 + 33517481 = 33517840
383 + 33517457 = 33517840
467 + 33517373 = 33517840
569 + 33517271 = 33517840

Showing the first eight; more decompositions exist.
