Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33527840, here are decompositions:

43 + 33527797 = 33527840
109 + 33527731 = 33527840
163 + 33527677 = 33527840
223 + 33527617 = 33527840
373 + 33527467 = 33527840
397 + 33527443 = 33527840
499 + 33527341 = 33527840
523 + 33527317 = 33527840

Showing the first eight; more decompositions exist.
