Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33493918, here are decompositions:

5 + 33493913 = 33493918
11 + 33493907 = 33493918
41 + 33493877 = 33493918
47 + 33493871 = 33493918
89 + 33493829 = 33493918
317 + 33493601 = 33493918
389 + 33493529 = 33493918
677 + 33493241 = 33493918

Showing the first eight; more decompositions exist.
