Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33493140, here are decompositions:

19 + 33493121 = 33493140
59 + 33493081 = 33493140
137 + 33493003 = 33493140
223 + 33492917 = 33493140
251 + 33492889 = 33493140
269 + 33492871 = 33493140
277 + 33492863 = 33493140
293 + 33492847 = 33493140

Showing the first eight; more decompositions exist.
