Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33554768, here are decompositions:

7 + 33554761 = 33554768
31 + 33554737 = 33554768
127 + 33554641 = 33554768
241 + 33554527 = 33554768
397 + 33554371 = 33554768
421 + 33554347 = 33554768
547 + 33554221 = 33554768
601 + 33554167 = 33554768

Showing the first eight; more decompositions exist.
