Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33518888, here are decompositions:

157 + 33518731 = 33518888
211 + 33518677 = 33518888
349 + 33518539 = 33518888
397 + 33518491 = 33518888
439 + 33518449 = 33518888
499 + 33518389 = 33518888
619 + 33518269 = 33518888
751 + 33518137 = 33518888

Showing the first eight; more decompositions exist.
