Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33511640, here are decompositions:

13 + 33511627 = 33511640
31 + 33511609 = 33511640
79 + 33511561 = 33511640
109 + 33511531 = 33511640
193 + 33511447 = 33511640
241 + 33511399 = 33511640
541 + 33511099 = 33511640
601 + 33511039 = 33511640

Showing the first eight; more decompositions exist.
