Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33494140, here are decompositions:

23 + 33494117 = 33494140
41 + 33494099 = 33494140
83 + 33494057 = 33494140
89 + 33494051 = 33494140
167 + 33493973 = 33494140
227 + 33493913 = 33494140
233 + 33493907 = 33494140
263 + 33493877 = 33494140

Showing the first eight; more decompositions exist.
