Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33547140, here are decompositions:

23 + 33547117 = 33547140
31 + 33547109 = 33547140
43 + 33547097 = 33547140
47 + 33547093 = 33547140
59 + 33547081 = 33547140
83 + 33547057 = 33547140
89 + 33547051 = 33547140
97 + 33547043 = 33547140

Showing the first eight; more decompositions exist.
