Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33558440, here are decompositions:

67 + 33558373 = 33558440
193 + 33558247 = 33558440
229 + 33558211 = 33558440
277 + 33558163 = 33558440
373 + 33558067 = 33558440
379 + 33558061 = 33558440
397 + 33558043 = 33558440
499 + 33557941 = 33558440

Showing the first eight; more decompositions exist.
