Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33511172, here are decompositions:

43 + 33511129 = 33511172
73 + 33511099 = 33511172
181 + 33510991 = 33511172
199 + 33510973 = 33511172
223 + 33510949 = 33511172
271 + 33510901 = 33511172
421 + 33510751 = 33511172
433 + 33510739 = 33511172

Showing the first eight; more decompositions exist.
