Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33545678, here are decompositions:

79 + 33545599 = 33545678
151 + 33545527 = 33545678
181 + 33545497 = 33545678
277 + 33545401 = 33545678
307 + 33545371 = 33545678
349 + 33545329 = 33545678
367 + 33545311 = 33545678
487 + 33545191 = 33545678

Showing the first eight; more decompositions exist.
