Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33543380, here are decompositions:

7 + 33543373 = 33543380
43 + 33543337 = 33543380
67 + 33543313 = 33543380
127 + 33543253 = 33543380
181 + 33543199 = 33543380
193 + 33543187 = 33543380
223 + 33543157 = 33543380
313 + 33543067 = 33543380

Showing the first eight; more decompositions exist.
