Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33511238, here are decompositions:

67 + 33511171 = 33511238
109 + 33511129 = 33511238
139 + 33511099 = 33511238
151 + 33511087 = 33511238
181 + 33511057 = 33511238
199 + 33511039 = 33511238
337 + 33510901 = 33511238
457 + 33510781 = 33511238

Showing the first eight; more decompositions exist.
